The '''{{Specs|name}}''' is a rank {{Specs|rank}} Italian tank destroyer {{Battle-rating}}. It was introduced in [[Update "Starfighters"]]. The M18 "Hellcat" was the epitome of the American tank destroyer doctrine, it was very fast, very mobile, and has a powerful gun, though with a large trade-off with only 12.7 mm (0.5 inches) of armour.
 
  
−
The M18 "Hellcat" compensates the lack of anti-tank capability by having absurdly fast maneuverability. While it looses access to APCR, this is justified seeing how it doesn't face very armored vehicles, the likes of [[Panther D|Panther D]], [[Tiger H1|Tiger H1]].

−
Unlike the other tank destroyers known in the game, the M18 "Hellcat" has access to a 360° traversable turret, allowing players to have a greater arc of fire than a typical casemate tank destroyer like the [[StuG III G|StuG III]], but at the expense of a slightly higher profile. Americans tank destroyers also have very high maneuverability compared to other nation's tank destroyers, allowing it to flank the enemy.

The main weak point of M18 is its very thin armor, a feature that actually allows the M18 to reach its high speed. The thin armour makes it possible for any enemy tanks to penetrate the vehicle. A single hit would destroy many critical components in the M18 or cripple the crew.  The only saving grace with this extremely thin ammunition is that standard AP rounds may over-penetrate the armor, doing minimal damage to the internals. Thus, when facing the M18, it's best to use AP rounds with explosive fillers or HE and HEAT rounds while avoiding usage of pure AP rounds.

The {{PAGENAME}} has extremely thin armour throughout its construction. As such, a player with the M18 should throw away any notion of trying to survive a shot and instead aim to avoid being hit at all. With an open-top construction and the placement of certain crew members, even enemy machine gun rounds can knock out the crew members inside and lower combat efficiency.

The thin armour is also both a blessing and a curse for the vehicle. It is a curse as it means the vehicle can suffer through the hull-break mechanics. A single shell has the potential of knocking out the M18 instantly regardless of how many crew member it defeats. The blessing is that if the enemy kinetic round hits the M18 and does not meet the requirements for a hull-break, the M18 may end up with minimum critical damage such as a damaged module or crew member. As such, there can be second chances for this vehicle, but as mentioned, this should not be relied upon as a combat strategy.

The thin armour is also both a blessing and a curse for the vehicle. It is a curse as it means the vehicle can suffer through the overpressure damage mechanics. A single HE shell has the potential of knocking out the M18 instantly regardless of its calibre. The blessing is that if the enemy kinetic round hits the M18 without triggering the fuze, the M18 may end up with minimum critical damage such as a damaged module or crew member. As such, there can be second chances for this vehicle, but this should not be relied upon as a combat strategy.
  
 
With five crew members, the M18 has a standard amount of crew to survive off of. Three are essential for combat efficiency: the gunner, loader, and driver. The commander operates the cupola machine gun and if knocked out will cause the machine gun to no longer function. This will be a constant occurrence due to the position of the commander model with the torso exposed above the turret, and so enemy machine gun rounds can hit and incapacitate the commander from the vehicle's functions.

The M18's module configuration is rather standard with the transmission in front and engine in the back. The spread out nature means there are more "wiggle room" for kinetic shells to hit and pass through around the modules, but it also means that any part of the M18 exposed can be hit and induce a hull-break.

Though the previous section on armour may imply poor survivability, the {{PAGENAME}}'s shining trait will be in its mobility. It produces enough engine horsepower to become a speed demon on the battlefield, quickly traversing through rough terrain to get to advantageous positions to ambush enemies that are just starting to get to the fight.

As with every ground vehicle Parts and FPE are an absolute top priority. Following that, depending on player preferences, one of 3 should be researched: Horizontal Drive (close-range, flanking), Suspension (medium-range) or Adjustment of Fire (long-range of a typical engagements). Following this the goal is to get rank IV mobility improvements in order Filters -> Engine -> Transmission. On rank III, along the way, the Crew Replenishment should be prioritized, as its an open-top vehicle, so it will suffer significant causalities from enemy airplanes. If your preferred engagement range is above 700 m then the Elevation Mechanism should be researched. Otherwise: Mobility upgrades are the most important, shells are the lowest priority, as even the situational advantage of the M93 shot is not worth researching over improved mobility, or even accuracy.

76 mm M1 is an extremely capable gun with a high damage potential and a very good gun handling. It can be found on tanks used up to battle rating 6.0, making it one of the most widely used guns throughout the battle ratings and with M18 being the first tanks to use it - it gives it a very high staying power throughout battle ratings. Once upgraded, the turret has very fair guidance in both: horizontal and vertical axis allowing to quickly catch pot-shots, though given exceptional mobility of the platform even it struggles to catch up with the near-instant hull rotation.

===== Ammunition =====
 
−
M18 comes with an exceptionally good stock shell, allowing it to unleash its full potential pretty much right off the bat. Additional unlocks are more specialized.
 
  
−
* M62 shell - {{Annotation|APCBC|Armour-Piercing Capped Ballistic Capped}} - The best anti-tank shell, also the stock round. It has very good penetration and an excellent post-penetration effect.
+
==== Ammunition ====
−
* M42A1 shell - {{Annotation|HE|High-Explosive fragmentation shell}} - The best round for dealing with unarmored targets or unarmored sections of vehicles. It should be used carefully, as everything over 10 mm armour can negate its effects. Typically M62 is superior.
+
 
−
* M79 shot - {{Annotation|AP|Armour-Piercing}} - Round inferior in every way to the M62, it's in-game largely for historical reasons.
+
* M79 shot - {{Annotation|AP|Armour-Piercing}} - Stock round, has decent penetrative power but no explosive filler. Replace with the M62 shell as soon as possible.
−
* M93 shot - {{Annotation|APCR|Armour-Piercing Composite Rigid shell}} - Round trades a significantly lower post-penetration effect for a 20% increase in penetration and flatter flight path.
+
* M42A1 shell - {{Annotation|HE|High-Explosive fragmentation shell}} - The best round for dealing with unarmoured targets or unarmoured sections of vehicles. It should be used carefully, as everything over 10 mm armour can negate its effects. Typically M62 is superior.

When fighting in battle rating 4.7 and 5.0 it's best to take only 17 shells, which allows to empty turret and sides of the tank from shells, notably increasing survivalist. In battle ratings around 6.0, it doesn't matter how many rounds are loaded, as most hits against the tank will prove deadly regardless.

The M18's speed is its best ally. This speed has to be used for flanking manoeuvres and relocate. Not for trying to cross an open field, that will leave it open to enemy fire, speed is not a substitute for armour.

'''Relocate:'''  
+
'''Relocate:''' - This movement will have to be done again and again. Choose a good spot wisely, remove the foliage if necessary to get a clear field of fire. When in the fire spot, use the gun depression and stay in a hull-down position until a target is located. Once a target is locked on, aim at critical components. Try to immobilize the enemy by firing at the engine or transmission, or remove their firepower by shooting the gun or breech, or for instant destruction with a shot to the ammo storage. The last option can work very well or not, as skilled players only carry a few rounds of ammo. If positive that the enemy hasn't discovered the firing spot, go for another shot. Stay attentive that none of the enemy's teammates has also located the firing spot. If detected, hide immediately and relocate.

'''Flanking:'''
 
−
 
 
−
* Flanking is the most dangerous manoeuvre of all because the vehicle will have to be exposed as it moves to the enemy's rear, but it is very effective when it's coordinated with other vehicles. A distraction is needed to gain the enemy's attention while the M18 makes its move. Isolated enemy units are very vulnerable to this tactic. Using the M18 speed to get to the rear and as the enemy heads toward the objective, the firing perspective should give a very clear view of the enemy's side armour. A good shot with the M62 APCBC shell could knock out the enemy rather quickly, but if using solid AP shots like the M79, aim at critical components on mobility and firepower before knocking out the crew or ammo stowage.

'''Flanking:''' is the most dangerous manoeuvre of all because the vehicle will have to be exposed as it moves to the enemy's rear, but it is very effective when it's coordinated with other vehicles. A distraction is needed to gain the enemy's attention while the M18 makes its move. Isolated enemy units are very vulnerable to this tactic. Using the M18 speed to get to the rear and as the enemy heads toward the objective, the firing perspective should give a very clear view of the enemy's side armour. A good shot with the M62 APCBC shell could knock out the enemy rather quickly, but if using solid AP shots like the M79, aim at critical components on mobility and firepower before knocking out the crew or ammo stowage.

* Flat terrain means that the Hellcat will become an easy target for virtually any vehicle by exposure, especially when not moving or when moving in a straight line. Open plains are the bane of the Hellcat. Whenever possible, one should try to stay amongst hills.

As with every ground vehicle Parts and FPE are an absolute top priority. Following that, depending on player preferences, one of 3 should be researched: Horizontal Drive (close-range, flanking), Suspension (medium-range) or Adjustment of Fire (long-range of a typical engagements). Following this the goal is to get rank IV mobility improvements in order Filters -> Engine -> Transmission. On rank III, along the way, the Crew Replenishment should be prioritized, as its an open-top vehicle, so it will suffer significant causalities from enemy airplanes. If your preferred engagement range is above 700m then the Elevation Mechanism should be researched. Otherwise: Mobility upgrades are the most important, shells are the lowest priority, as even the situational advantage of the M93 shot is not worth researching over improved mobility, or even accuracy.

===US Tank Destroyer Doctrine===
+
Throughout the Second World War, the USA would be experimenting with many different tanks and military vehicles, in the hopes they'd be put into service to help the war effort. In December of 1941, a new requirement from the US high command would initially request a vehicle which incorporated the Christie suspension system, and armed with a 37 mm gun. Considering that during those times, for most new vehicles, they were often derived from a previous existing design, mainly done to save time and money, this requirement instead called for a radical new tank design rather than a derivative of an existing tank, such as the [[M4|M4 Sherman]]. Whilst the war was ongoing, the US high command would begin to alter the requirements, mainly due to more powerful enemy vehicles showing up on the battlefield. One of the first changes done during the development was to introduce the new and innovative Torsion bar suspension made by the Buick Motor Division, who were part of General Motors. Later another change was to mount the British made [[Ordnance QF 6-pounder Mk.III (57 mm)|QF 6-pounder gun]] which at the time would be in use on the British [[Churchill Mk III]] tanks. This would lead to one of the prototype vehicles to be made, which would be called T49 GMC. Tests proved to yield adequate results but still weren't up to standard, the US Army wanted the heavier [[M3 (75 mm)|75 mm gun]] which at the time would be mainly used on the various Shermans in service. In the end this lead to the T67 GMC prototype, this got closer to the requirements but the US high command felt that more could be done. Finally, the US army decided to mount the [[M1 (76 mm)|76 mm gun]] also in development for the Sherman onto the prototype, which now was known as the T70 GMC. Obviously changes to hull shape and turret had to be done, mainly to accommodate all the new requirements and armament set out by the US high command. After some refinement in the design, the US high command eventually approved the prototype for service and finally designated the vehicle as the M18 GMC. The vehicle started production in mid-1943, which went on until October 1944 with a grand total 2,507 units produced. They'd be extensively used, and would yield great results for the most part.

The self-propelled anti-tank doctrine established by the US military called for fast, powerful vehicles able to stop the German blitzkrieg tactics by ambushing the attacking tank forces. This doctrine, known as the "Tank Destroyer Doctrine", called for anti-tank forces to be held in reserve to blunt the massed Panzer attacks that many in the War Department believed was the key to German victory in France in 1940. The concentration of antitank weaponry away from the frontline was eventually determined to be an unnecessary weakness, and the solution was to keep a few anti-tank guns in the front-line as the first defence, while a large reserve of mobile tank destroyers would move in at the location where a German tank breakthrough is happening to ambush and destroy the enemy forces. This role led to the desire for a fast vehicle with a powerful gun and mobility. Minimal emphasis was placed on armour, as the doctrinal role of tank destroyers was to respond rapidly to an enemy armoured breakthrough; heavy armour would only hinder a timely response. The development of a purpose-built tank destroyer languished in bureaucratic limbo for the early years of the war (a delay caused by poor designs such as the M5 Cletrac and bureaucratic infighting between the various departmental cliques), and consequently, the majority of self-propelled tank destroyers were expedients derived from the M4 Sherman chassis. The most common tank destroyer was the [[M10 GMC|M10 GMC]], made from the [[M4A2|M4 Sherman]] hull and armed with a 3-inch M1918 gun. Although perfectly capable and welcome addition for frontline forces, it was no faster than an ordinary Sherman tank. The tank destroyers would in 1944 finally receive their purpose-built self-propelled tank destroyer in 1944: the M18 Hellcat.<ref name="ZalogaM18" />

The story of the Italian M18, also known as the 'Semovente da 76/52', would officially start in the post-war period. The Italian army, and its armoured divisions for the most part ceased to exist, although the US and other allied countries would slowly begin to re-equip the Italian army with surplus equipment. Italy would also begin to restore some of their own WW2 era equipment which managed to survive the war into working order and promptly put them into service. As the early dawn of the Cold War was looming, and the Italian armed forces being fairly weak, it was decided that a series of rearmament programs begin. Luckily, the USA had a lot of surplus equipment that they did not need anymore and were willing to invest heavily in rearming the Italian army through the 'MAP' (Military Assistance Program). It was decided that Italy would receive a total of 130 M18 GMCs, which would all be finally delivered during July of 1952. The M18 Hellcats were renamed to 'Semovente da 76/52', re-painted, and as many Italian vehicles, had the side-skirts removed. In terms of service, the Semovente da 76/52 would be allocated to the 155th Artillery Regiment of the 5th Army Corps which garrisoned the regions of Veneto and Friuli Venezia Giulia near the Eastern border. They'd have a good reputation, and loosely followed standard Italian doctrine, which usually entails light vehicles with a good gun. Although they would have likely been in the front lines if a war between East and West ever broke out, they never saw combat action. During training, some Italian versions of the vehicle would install a machine gun, usually a Browning of some sort, onto the cannon. They'd be slowly be phased out for more modern designs who could be used as tank destroyers as the Cold War raged on.

The origin of the M18 design came as early as December 1941 with the requirement of a Christie suspension and a 37 mm gun. This requirement called for a radical new tank design rather than a derivative of the [[M4|M4 Sherman]]. These requirements changed as the war progressed, the first change was to the new and innovative Torsion bar suspension from Buick Motor Division from General Motors and another change was to mount the British [[Ordnance_QF_6-pounder_Mk.III_(57_mm)|QF 6-pounder gun]] then in use on their [[Churchill_Mk_III|Churchill Mark III]] tanks, the developed prototype vehicle was called the ''T49 GMC''. Then the US Army wanted the heavier [[M3_(75_mm)|75 mm gun]] used on the Shermans on it, this prototype was designated the ''T67 GMC''. Finally, the army decided to mount the [[M1_(76_mm)|76 mm gun]] also in development for the Sherman onto the prototype, now known as ''T70 GMC''. Changes to hull shape and turret took place to accommodate all these new requirements and armament, but it eventually was approved for service and finally renamed as the '''M18 GMC''' and started production in mid-1943, which went on until ending in October 1944 with 2,507 units produced. A variant called the ''M39 Armored Utility Vehicle'' was also produced, its turret was removed for space for cargo, 8 personnel, or to tow guns.

===Combat usage===

== Media ==

These vehicles saw combat debut in the summer of 1944, where they are given the unofficial nickname '''"Hellcat"''' by the crews using them. Unlike the [[M10 GMC|M10 tank destroyer]] that was built before it, the M18 GMC was purely made for emphasis on speed. Armour was restricted down to a maximum of 1-inch (25 mm) on the turret front while the rest of the body plating is a measly .50-inches thick (12.7 mm). The turret was also an open-top design similar to the M10 tank destroyer, meaning the crew are left exposed to the elements and enemy fire and shrapnel. These faults were mitigated by the fact that as its role as a tank destroyer, it was to have minimum contact with infantry and ambush enemy tanks in concealed position rather than face them in an offensive operation. Nevertheless, the M18 GMC was well-liked by the crew for its 76 mm cannon, which allows it to destroy the newer German [[Tiger H1|Tiger Is]] and [[Panther D|Panthers]] tanks from the front with HVAP ammo (though the Panther at close range only) when unable to flank around to the side or rear of these tanks. The speed was also astounding, reaching 55 miles per hour maximum, this makes the M18 GMC the fastest armoured fighting vehicle in World War II.

While use in the Pacific theatre was limited due to the inadequate armour of Japanese tanks, it saw most of its service in the European theatre against Nazi Germany. Due to the lack in armour and emphasis on speed, the M18 crews utilize the "shoot and scoot" tactic in attacking the enemy from one position and quickly move to another before the enemy could find their initial firing position, this tactic confuses the German tanks, and could even lead them to believe there is more armoured enemy than what it appears. The M18 GMCs were present during the Battle of Arracourt in France as the 704th Tank Destroyer Battalion. Lt. Edwin Leiper led an M18 platoon of C Company and in the battle knocked a total of 15 German tanks for the loss of three M18; six of these German tank kills, most of which were Panthers, were credited to one M18 led by Sgt Henry R. Hartman. The M18 also played a crucial part in the Battle of the Bulge, where its top speed of 55 mph was finally put to good use in bypassing the enemy forces. Four M18 tank destroyers of the 705th Tank Destroyer Battalion assisted the 506th Parachute Infantry Regiment in attacking the 2nd Panzer Divison and their support to kill the fuel lines to the German tanks. The overall attack had the M18 GMC credited with at least 24 tank kills of the 30 total inflicted in the attack.

Overall, the M18 GMC proved itself by having the highest kill-to-loss ratio to any other tanks and tank destroyer in American service, making it the most effective tank destroyer in American service. However, like its other tank destroyer brethren, it soon found itself obsolete along with the entire tank destroyer doctrine. Mainly due to increasing prevalence of well-armoured tanks that could do its job more efficiently such as the [[M26|M26 Pershing]], but also the lack of German AFVs at the time of the war and a study on ammo usage indicates that the tank destroyers spent more time supporting infantry with high-explosive shells than killing tanks with armour-piercing, rendering the anti-tank section an unnecessary component in the modernizing armoured forces.

A self-propelled artillery/tank destroyer mount based on the M24 tank. It was part of the American arsenal during World War II. It was produced from the middle of 1943 to October, 1944 and was used in combat operations in Italy and northern Europe. Its primary gun was the M1 76mm cannon, as was the case with late-model Sherman tanks. This tank destroyer featured very light armor, but the M18 was nevertheless the fastest armored vehicle in World War II.

The Hellcat was the most effective anti-tank SPG in the American army despite its extreme vulnerability and the fact that its 76mm cannon was unable to penetrate the armor of late German tanks. The vehicle stood out for its speed and maneuverability. Able to accelerate and change direction quickly, the Hellcat could easily outflank German tanks or even get behind them, whereas the rotation speed of the German tanks was not fast enough to attack the M18 and the M1 cannon could penetrate the enemy’s weak points with relative ease.

Description

The Cannone da 76/52 Semovente M18 is a rank IV Italian light tank with a battle rating of 5.3 (AB) and 6.0 (RB/SB). It was introduced in Update "Starfighters".

The M18 "Hellcat" was the epitome of the American tank destroyer doctrine, it was very fast, very mobile, and has a powerful gun, though with a large trade-off with only 12.7 mm (0.5 inches) of armour.

The M18 "Hellcat" compensates the lack of anti-tank capability by having absurdly fast manoeuvrability. While it loses access to APCR, this is justified seeing how it doesn't face very armoured vehicles, the likes of Panther D, Tiger H1.

Unlike the other tank destroyers known in the game, the M18 "Hellcat" has access to a 360° traversable turret, allowing players to have a greater arc of fire than a typical casemate tank destroyer like the StuG III, but at the expense of a slightly higher profile. Americans tank destroyers also have very high manoeuvrability compared to other nation's tank destroyers, allowing it to flank the enemy.

The main weak point of M18 is its very thin armour, a feature that actually allows the M18 to reach its high speed. The thin armour makes it possible for any enemy tanks to penetrate the vehicle. A single hit would destroy many critical components in the M18 or cripple the crew. The only saving grace is that standard AP rounds may over-penetrate the armour, doing minimal damage to the internals. Thus, when facing the M18, it's best to use AP rounds with explosive fillers or HE and HEAT rounds while avoiding usage of pure AP rounds.

Visibility82 %

The M18 (Italy) has extremely thin armour throughout its construction. As such, a player with the M18 should throw away any notion of trying to survive a shot and instead aim to avoid being hit at all. With an open-top construction and the placement of certain crew members, even enemy machine gun rounds can knock out the crew members inside and lower combat efficiency.

The thin armour is also both a blessing and a curse for the vehicle. It is a curse as it means the vehicle can suffer through the overpressure damage mechanics. A single HE shell has the potential of knocking out the M18 instantly regardless of its calibre. The blessing is that if the enemy kinetic round hits the M18 without triggering the fuze, the M18 may end up with minimum critical damage such as a damaged module or crew member. As such, there can be second chances for this vehicle, but this should not be relied upon as a combat strategy.

With five crew members, the M18 has a standard amount of crew to survive off of. Three are essential for combat efficiency: the gunner, loader, and driver. The commander operates the cupola machine gun and if knocked out will cause the machine gun to no longer function. This will be a constant occurrence due to the position of the commander model with the torso exposed above the turret, and so enemy machine gun rounds can hit and incapacitate the commander from the vehicle's functions.

The M18's module configuration is rather standard with the transmission in front and engine in the back. The spread out nature means there are more "wiggle room" for kinetic shells to hit and pass through around the modules.

Armour type:

  • Rolled homogeneous armour
  • Cast homogeneous armour (Gun mantlet)
Armour Front (Slope angle) Sides Rear Roof
Hull 12.7 mm (39-64°) Front glacis
12.7 mm (23-52°) Lower glacis 		12.7 mm (23-26°) Top

Notes:

  • Suspension wheels and tracks are 15 mm thick.
  • Belly armour is 5 mm thick.
  • The hull underside right above the tracks are only 8 mm thick.
  • Tracks are attached the turret rear, granting some 15 mm in thickness.

Though the previous section on armour may imply poor survivability, the M18 (Italy)'s shining trait will be in its mobility. It produces enough engine horsepower to become a speed demon on the battlefield, quickly traversing through rough terrain to get to advantageous positions to ambush enemies that are just starting to get to the fight.

The vehicle displays great mobility when driving forwards and backwards, and so it can perform quick exits from a compromised position.

As with every ground vehicle Parts and FPE are an absolute top priority. Following that, depending on player preferences, one of 3 should be researched: Horizontal Drive (close-range, flanking), Suspension (medium-range) or Adjustment of Fire (long-range of a typical engagements). Following this the goal is to get rank IV mobility improvements in order Filters -> Engine -> Transmission. On rank III, along the way, the Crew Replenishment should be prioritized, as its an open-top vehicle, so it will suffer significant causalities from enemy airplanes. If your preferred engagement range is above 700 m then the Elevation Mechanism should be researched. Otherwise: Mobility upgrades are the most important, shells are the lowest priority, as even the situational advantage of the M93 shot is not worth researching over improved mobility, or even accuracy.

76 mm M1 cannon
Ammunition45 rounds

Main article: M1 (76 mm)

The 76 mm M1 is an extremely capable gun with a high damage potential and a very good gun handling. Once upgraded, the turret has very fair guidance in both: horizontal and vertical axis allowing to quickly catch pot-shots, though given exceptional mobility of the platform even it struggles to catch up with the near-instant hull rotation.

Ammunition

  • M79 shot - AP - Stock round, has decent penetrative power but no explosive filler. Replace with the M62 shell as soon as possible.
  • M42A1 shell - HE - The best round for dealing with unarmoured targets or unarmoured sections of vehicles. It should be used carefully, as everything over 10 mm armour can negate its effects. Typically M62 is superior.
  • M62 shell - APCBC - The best anti-tank shell. It has very good penetration and an excellent post-penetration effect.

  • Turret empty: 37 (+8) shells.
  • When fighting in downtiers it's best to take only 17 shells, which allows the turret and sides of the tank to be empty of shells, notably increasing survivability.

Usage in battles

Before all, avoid colourful or bright decals. Camouflage is the main part of the M18's defence. Chances for good performance in battle are: be "invisible", fast and effective. The M18's speed is its best ally. This speed has to be used for flanking manoeuvres and relocate. Not for trying to cross an open field, that will leave it open to enemy fire, speed is not a substitute for armour.

Relocate: - This movement will have to be done again and again. Choose a good spot wisely, remove the foliage if necessary to get a clear field of fire. When in the fire spot, use the gun depression and stay in a hull-down position until a target is located. Once a target is locked on, aim at critical components. Try to immobilize the enemy by firing at the engine or transmission, or remove their firepower by shooting the gun or breech, or for instant destruction with a shot to the ammo storage. The last option can work very well or not, as skilled players only carry a few rounds of ammo. If positive that the enemy hasn't discovered the firing spot, go for another shot. Stay attentive that none of the enemy's teammates has also located the firing spot. If detected, hide immediately and relocate.

Flanking: is the most dangerous manoeuvre of all because the vehicle will have to be exposed as it moves to the enemy's rear, but it is very effective when it's coordinated with other vehicles. A distraction is needed to gain the enemy's attention while the M18 makes its move. Isolated enemy units are very vulnerable to this tactic. Using the M18 speed to get to the rear and as the enemy heads toward the objective, the firing perspective should give a very clear view of the enemy's side armour. A good shot with the M62 APCBC shell could knock out the enemy rather quickly, but if using solid AP shots like the M79, aim at critical components on mobility and firepower before knocking out the crew or ammo stowage.

Avoid flat terrain - Flat terrain means that the Hellcat will become an easy target for virtually any vehicle by exposure, especially when not moving or when moving in a straight line. Open plains are the bane of the Hellcat. Whenever possible, one should try to stay amongst hills.

Pros and cons

Pros:

  • Overall mobility is superb, with very responsive manoeuvring that allows the Hellcat to excel in flanking manoeuvres
  • Fast reload speed and turret traverse
  • M62 APCBC round has great penetration and lots of explosive fillers, rarely requiring more than one penetrating shot to kill common tanks like T-34-85, M4A3, Cromwell, IS-1 and IS-2
  • Low profile, reducing target size and allows it to hide behind small bushes or rocks easily
  • The nature of its thin armour means AP rounds have a tendency to pass straight through without damaging modules, and an APHE fuse may not even be triggered. For example the Soviet 122 mm tend to overpenetrate, dealing little damage

Cons:

  • Thin armour means rapid-fire autocannons, heavy machine guns, and aerial weapons could easily shred it. Beware of the ZSD63 and the GAZ trucks
  • Commander is exposed at the 0.50 cal machine gun mount, and knocking him out would render the weapon useless
  • Open-top construction means the crew is vulnerable to to aircraft strafing and overpressure: artillery strikes and chemical shells can knock out easily the vehicle
  • Gun has poor penetration in an uptier, often can't penetrate anything frontally unless hitting a weak spot. The M4A3E2 and M26 are frontally immune to this 76 mm M1
  • Doesn't have access to APCR unlike its American counterpart
  • Rarely reaches 50 km/h in Realistic Battles, even in a straight line, therefore can be outran by the Sd.Kfz.234 series
  • A moment of immobility due to a damaged engine or transmission could be a sign of impending doom for the M18

History

Main article: History of the M18 GMC

Throughout the Second World War, the USA would be experimenting with many different tanks and military vehicles, in the hopes they'd be put into service to help the war effort. In December of 1941, a new requirement from the US high command would initially request a vehicle which incorporated the Christie suspension system, and armed with a 37 mm gun. Considering that during those times, for most new vehicles, they were often derived from a previous existing design, mainly done to save time and money, this requirement instead called for a radical new tank design rather than a derivative of an existing tank, such as the M4 Sherman. Whilst the war was ongoing, the US high command would begin to alter the requirements, mainly due to more powerful enemy vehicles showing up on the battlefield. One of the first changes done during the development was to introduce the new and innovative Torsion bar suspension made by the Buick Motor Division, who were part of General Motors. Later another change was to mount the British made QF 6-pounder gun which at the time would be in use on the British Churchill Mk III tanks. This would lead to one of the prototype vehicles to be made, which would be called T49 GMC. Tests proved to yield adequate results but still weren't up to standard, the US Army wanted the heavier 75 mm gun which at the time would be mainly used on the various Shermans in service. In the end this lead to the T67 GMC prototype, this got closer to the requirements but the US high command felt that more could be done. Finally, the US army decided to mount the 76 mm gun also in development for the Sherman onto the prototype, which now was known as the T70 GMC. Obviously changes to hull shape and turret had to be done, mainly to accommodate all the new requirements and armament set out by the US high command. After some refinement in the design, the US high command eventually approved the prototype for service and finally designated the vehicle as the M18 GMC. The vehicle started production in mid-1943, which went on until October 1944 with a grand total 2,507 units produced. They'd be extensively used, and would yield great results for the most part.

The story of the Italian M18, also known as the 'Semovente da 76/52', would officially start in the post-war period. The Italian army, and its armoured divisions for the most part ceased to exist, although the US and other allied countries would slowly begin to re-equip the Italian army with surplus equipment. Italy would also begin to restore some of their own WW2 era equipment which managed to survive the war into working order and promptly put them into service. As the early dawn of the Cold War was looming, and the Italian armed forces being fairly weak, it was decided that a series of rearmament programs begin. Luckily, the USA had a lot of surplus equipment that they did not need anymore and were willing to invest heavily in rearming the Italian army through the 'MAP' (Military Assistance Program). It was decided that Italy would receive a total of 130 M18 GMCs, which would all be finally delivered during July of 1952. The M18 Hellcats were renamed to 'Semovente da 76/52', re-painted, and as many Italian vehicles, had the side-skirts removed. In terms of service, the Semovente da 76/52 would be allocated to the 155th Artillery Regiment of the 5th Army Corps which garrisoned the regions of Veneto and Friuli Venezia Giulia near the Eastern border. They'd have a good reputation, and loosely followed standard Italian doctrine, which usually entails light vehicles with a good gun. Although they would have likely been in the front lines if a war between East and West ever broke out, they never saw combat action. During training, some Italian versions of the vehicle would install a machine gun, usually a Browning of some sort, onto the cannon. They'd be slowly be phased out for more modern designs who could be used as tank destroyers as the Cold War raged on.
