The '''M56 Scorpion''' is a Rank IV American tank destroyer with a battle rating of 6.3 (AB) 6.7 (RB/SB). It was introduced in [[Update 1.63 "Desert Hunters"]].  
+
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.97 "Viking Fury"]].
  
−
Though one of the lightest tank destroyers in the game, its 90 mm gun gives it a very powerful punch, especially when using the HEATFS round, which penetrates 320 mm of armour.
+
The Sav m/43 (1946) is essentially identical to the [[Sav m/43 (1944)]] with the important exception of the gun: instead of the 75 mm field gun, it features a 105 mm howitzer.

=== Survivability and armour ===
−
Fitting the definition of a glass cannon, the M56 has virtually no armour to speak of, as the majority of the tank comprises structural steel not meant to protect the crew and has a weak armour modifier (x0.45 KE), which renders it near useless in protecting internal components from incoming fire of any caliber, with the exception of high-angle impacts from rifle-caliber rounds. This description also applies to the only armour plate found on the entire tank, the gun shield, as the 5 mm thick plate with 12 mm of bullet-proof glass will only be able to stop rifle-caliber bullets from mid to long ranges.
+
<!-- ''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.'' -->
 +
The Sav m/43 (1946) has up to 50 mm of armour in front, which is capable of deflecting shots if angled, but should not be relied on. It should be noted that the engine deck is only 10 mm thick, and can be penetrated by aircraft heavy machine guns and cannon. The side armour is only 15 mm thick at most, and can also be penetrated quite easily by heavy machins guns and autocannon fire.
  
−
The crew consists of only 3 members, a driver on the port side of the gun breach, the gunner on the starboard side of the gun breach, and the commander sitting rather casually behind the driver.  If the tank is spotted and takes fire, expect the commander to be the first crew member down, since he is the most exposed of the three, sitting far away and above the gun shield.  Overall, survivability is very low and it is advised to take precautions to not take any fire from the opposition, making use of terrain and mobility when the battle gets heated.
+
Due to the cramped crew compartment and scattered ammunition within the compartment, any penetration by a shell is likely to cause critical damage to multiple modules and/or crew members.

The Sav m/43 is based on the chassis of the [[Strv m/41 S-II|Strv m/41]] and thus has a similar level of mobility. It is considerably heavier, however, and thus correspondingly more sluggish. While the forward top speed is adequate, the reverse speed is quite poor, making it hard to retreat.

The 1946 model of the Sav m/43 now features the '''10,5 cm kan m/44''', a 105 mm howitzer. It starts off with the very inadequate '''slpprj m/44''' APBC round. This round lacks the penetration or post-penetration damage to be competitive against the tanks the Sav m/43 faces; thus, it is of the utmost importance that the '''psgr m/49''' HEAT shell is unlocked as soon as possible. This round has an amazing 240 mm of penetration, the most of any round available to any Rank II tank in the game, and also has substantial post-penetration effects. There is also an HE round available that is effective against light vehicles and armour.

−
{{tankMobility|abMinHp= 284|rbMinHp= 177|<!--AoAweight=(optional) -->}}
+
The shells all have a relatively low muzzle velocity, and it can therefore be quite hard to hit moving targets at long range. Conversely, the substantial arc of the shell trajectories due to the low-velocity shells allows the Sav m/43 to sometimes hit targets hiding behind cover, or to fire from behind cover itself.
  
−
Where the M56 lacks in armour, it easily makes up for in mobility.  Its light weight and decently powered engine gives it a great power-to-weight ratio that lets it propel to top speed easily, even when stock.  You'll want to use this to gain access to favorable positions at the beginning of each match.  When your position is compromised, seek a retreat using its excellent reverse speed of -20 km/h and plan ahead your next route.
+
The heavier shells also result in a relatively long loading time compared to the 1944 model's 75 mm field gun.

===== Ammunition =====
+
==== Ammunition ====
−
The M54 cannon has 5 great flavors of destruction to choose from: APCR rounds, APCBC rounds, HEAT-FS rounds, HESH shells, and HE shells.
 
−
 
 
−
The '''M332 APCR''' shells are the basic rounds that you'll utilize when you first play your tank. Like any other APCR shell, with knowledge of the opposition's internal components such as gunner/driver locations and ammo racks, it is very useful against heavy foes with low-angle slopes in their armour profile.  But, it is very lacking in post-penetration damage. Though they are free to use, players may find the lack of post-penetration damage unfavorable, especially for a glass cannon who can't risk staying exposed for very long trying to pick apart an armoured foe.
 
−
 
 
−
The '''M82 APCBC''' shells are probably the first shells you'll unlock and will provide some relief if you've grown tired of the APCR's low post-pen damage. Like any other APHE, they possess good penetration at close to mid range with exceptional post-penetration damage for dealing with moderately armoured targets like many of the medium tanks you'll encounter at your battle rating. As soon as you unlock these, start carrying these as your standard round against most tanks while carrying a few of the above APCR for heavier foes, at least until you unlock the HEAT-FS round.
 
−
 
 
−
The '''M431 HEAT-FS''' should be '''the''' round you want to rely on to take care of most armoured foes you come across. Combining the best muzzle velocity, the greatest penetration, especially at long range, and decent post-penetration damage makes this the superior round to use in any mid-to-long range engagement. At close range or in ambush situations, with this shell being your loaded round, you will most likely cripple any target you may encounter. It may then be best to switch to APCBC or HESH (depending on the vehicle type) as a follow up to finish off the surviving target, unless the target still presents itself to be very armoured from your angle of fire (like the [[Maus]] or most heavies from the front). Especially so if you're conscious about your ammo bill after the battle as HEAT-FS are not the cheapest option.
 
−
 
 
−
The '''T142E3 HESH''' are an advanced high-explosive round that's capable of penetrating thick armour, even when it is highly-sloped. If you know your target possesses not a single plate of armour greater than 100mm, then these are the rounds to use to wreck them at any range, as these are equally effective against a valid target, including many medium tanks, any light tank and SPAA, and even some heavy tanks that rely on angles rather then raw thickness like an [[IS-3]] or [[AMX-50 Surbaisse]]. Just be sure to aim away from the tracks and suspension, as these modules can easily absorb any damage caused by HESH.
 
−
 
 
−
The '''M71 HE''' are just like your typical medium-caliber HE round, good against unarmoured targets like exposed crew members, hull-breakable vehicles, and air targets (should you be able to hit them), but not very useful outside of that. Though this is a free round with slightly better velocity (making it easier to use at long range), favor HESH instead when you can as it carries nearly as much of a payload and has increased versatility against more targets.
 
−
 
 
−
One last ammo type to mention are the '''M313 Smoke''' shells.  While not particularly useful for the role the M56 typically fills, they can still have good effect in long-range conflicts where a smoke to the face of an experienced enemy sniper can buy you or your allies time to bypass them in favor of a retreat or advancement towards the objective.
 
−
 
 
−
Overall, with all shells unlocked where you'll be employing mid to close range tactics, the typical recommended ammo composition can look something like this: 12 HEAT-FS, 4 APCBC, 5 HESH. For long-range engagements where you'll be playing more of a sniper role, it's best to forgo the APCBC in favor of bringing as much HEAT-FS as you can while throwing in a couple of smokes, though the smokes are optional. With this the recommended ammo composition for long-range engagements will look more like this: 20 HEAT-FS, 7 HESH, 2 Smokes.

 +
Like the preceding 1944 model, the Sav m/43 (1946) performs best in hull down positions, as it can use the gun depression to present a steeper angle on the frontal armour to increase its effective thickness. However, it commonly faces tougher opposition at this BR, including the very common [[T-34 (Family)|T-34]], [[M4A1]], and [[Pz.IV F2]] medium tanks, thus the armour should not be depended on in a slugging match against these tanks.
  
−
== Usage in the battles ==
+
Conversely, the 240 mm penetration on the HEAT round is capable of dealing with anything the Sav m/43 can encounter, even the heaviest of tanks. Hitting accurately with the low velocity shells will take practice, but since HEAT shells do not lose penetration with distance, the Sav m/43 is capable of crippling or destroying even the heaviest tanks at long range.
−
The M56 Scorpion is a fast, light tank destroyer with very little armour to speak of.  
 
  
−
A rapid volley from an enemy machine gun will knockout the three crew members with ease, if not carefully concealed. Its 90 mm M54 cannon is very able to disable enemy tanks at Rank IV. It is able to perform various destruction missions utilising various tactics. An M56 Scorpion is a dedicated airborne tank destroyer with airborne vehicle-based performance. The scorpion has a very stable and fast rate of acceleration on any terrain with a top speed of up to 28 MPH (45 km/h). With its high speed, it is very tempting to charge towards the capture point. When in a situation where a single enemy tank is present, unprotected, uncovered and separated from the opposing team. A rampaging Scorpion will be able to close in, then blow it up to kingdom come. However, caution must be undertaken throughout.
+
The side and rear armour is very thin (10-15 mm), and is very vulnerable to even heavy machine gun and autocannon fire. Exposing it to the enemy will lead to a quick demise, especially against the extremely common .50 cal M2 heavy machine gun found on a lot of American tanks.
  
−
Be wary that any tank, even if only armed with a machine gun, is capable of knocking out the M56 due to the exposed crew. One particular enemy to keep an eye for is the [[ASU-85]]. It's a complete soviet equivalent of the Scorpion. Its stock BR-372 APCBC-HE is hopeless against a Scorpion since it will always overpenetrate it & be unable to explode inside its engine or gun breech. Meanwhile the M82 APCBC-HE has the opposite effect against it, as the ASU-85 has 45 mm armour just like the [[T-34-85]], which was a big mistake. Even with inferior penetration, an M82 still has 1.5x more explosive warhead. Given enough penetration, it will always be able to cause it to explode frontally without much effort. Take a grain of salt when firing at the ASU-85 from its flank, since the M82 will also overpenetrate away. Loading the M71 HE is much better, since the explosion will spam the ASU-85's interior all over the place. Or if already loaded with M82 & an ASU-85 is approaching while showing its flank, aim for the engine to prevent it from recovering & escaping. Then blast it away.

=== Pros and cons ===
−
While the Arcade Battle environment is not favorable due to the marker system easily spotting the M56, it can still perform in flank and surprise attacks if employed properly. It still can snipe from far away & make score against some targets when the M431 HEATFS is unlocked. Be aware that many light tanks can hunt it down if caught in firing range, particularly the [[M41A1|M41A1 Bulldog]] and [[T92]].

The battle environment is more favorable in Realistic and Simulator Battles. It can completely perform full flanking manoeuvres even when stock, it can also snipe from far-distance without getting spotted easily. Using both tactics will guarantee a complete concealment from the enemy, while being able to launch '''M82 APCBC-HE''' at them with just a couple of shots. Closing in to the enemy is only viable if the enemy number has been completely depleted and/or are unable to insert reinforcements to cover their team.

Closing in, the Scorpion can out manoeuvre and outflank most, if not all enemy vehicles at its BR. When it is unable to flank due to tight enemy formation across the map, sniping is the best option.

It is recommended to Load: '''M431 HEATFS''' or '''M82''' if the enemy armour is insufficient to withstand such rounds. I.e. [[T-34-100]]). The reload time can help it to outgun any opposition, to withstand its sustained rate of fire. Especially if it is equipped with an Ace crew, which can reload around of 7 seconds. Also, try to use an ambush tactic. It can annihilate a whole team if used by a skilled player.

During World War II, the constant problem for the US Airborne divisions is that their anti-tank power was very minimal in the front lines. Though there were attempts to improve their firepower with towed anti-tank guns or airborne tanks like the [[M22|M22 ''Locust'']], the former proved too cumbersome and heavy while the latter proved too under-powered and weak. Thus, development began in April 1949 for a very lightly armoured vehicle to mount a hard-hitting gun with heavy emphasis on firepower, speed, and with as little weight as possible. This evolved into the development of a self-propelled 90 mm gun and the project was taken up by the Cadillac Motor Division of General Motors. The pilot vehicle developed were designated ''T101''.<ref name="ZalogaM551">Zaloga Steven. ''M551 Sheridan: US Airmobile Tanks 1941-2001'' Great Britain: Osprey Publishing Ltd., 2009</ref>

The first models were completed in 1953 and were tested in 1955. It was approved for service in 1958 and designated as the '''M56 90mm self-propelled gun''', or by its nickname '''"Scorpion"''' and its acronym '''SPAT''' ('''S'''elf-'''P'''ropelled '''A'''nti-'''T'''ank). It's main selling point was being light enough at only 7 tons to be lifted by helicopter or carried onto aircraft, allowing for parachute drops. As a rather specialized vehicle, it wasn't produced in large numbers, with only 150 units built from the Cadillac production line from 1953 to 1959.<ref name="ZalogaM551" />

===Usage===
 
−
The M56 Scorpion was issued out to airborne and anti-tank units from 1958 to the early 1960s. As a defensive weapon, the M56 Scorpion was never meant to venture out to seek and destroy enemy tanks, but its lack of armour was still criticized  by its crew, what with only a simple gun shield blocking the crew from getting shot by even small arms. The lightness of the vehicle was also bad for the extreme recoil of the 90 mm M54 gun, which would lift the entire vehicle off its front wheels.<ref name="ZalogaM551">Zaloga Steven. ''M551 Sheridan: US Airmobile Tanks 1941-2001'' Great Britain: Osprey Publishing Ltd., 2009</ref> An informal manual even recommends that when firing, the commander and loader should step off the vehicle to avoid being harmed by the lurching vehicle. The M56 Scorpion served America in combat during the Vietnam War in the 173rd Airborne Brigade, with 17 vehicles organized into three platoons. It served as a defensive role in most of American foreign bases until the advent of the anti-tank missile launchers such as the TOW, which proved more potent than the Scorpion, and was replaced in the late 1960s and early 70s.<ref name="ZalogaM551" />

The M56 Scorpions were also given out in limited numbers, with Morocco given 87 vehicles and Spain obtaining 5 in the Military Aid Program. Morocco used the Scorpions in the Western Sahara War, being the only foreign user of the M56 Scorpions.

At least 18 intact M56 Scorpions survive in the United States today, mainly in museums and in private collections.

Description

GarageImage Sav m43 (1946).jpg


The Stormartillerivagn m/43 (1946) is a rank II Swedish tank destroyer with a battle rating of 3.0 (AB/RB/SB). It was introduced in Update 1.97 "Viking Fury".

The Sav m/43 (1946) is essentially identical to the Sav m/43 (1944) with the important exception of the gun: instead of the 75 mm field gun, it features a 105 mm howitzer.

General info

Survivability and armour

The Sav m/43 (1946) has up to 50 mm of armour in front, which is capable of deflecting shots if angled, but should not be relied on. It should be noted that the engine deck is only 10 mm thick, and can be penetrated by aircraft heavy machine guns and cannon. The side armour is only 15 mm thick at most, and can also be penetrated quite easily by heavy machins guns and autocannon fire.

Due to the cramped crew compartment and scattered ammunition within the compartment, any penetration by a shell is likely to cause critical damage to multiple modules and/or crew members.

Mobility

Game Mode Max Speed (km/h) Weight (tons) Engine power (horsepower) Power-to-weight ratio (hp/ton)
Forward Reverse Stock Upgraded Stock Upgraded
Arcade 45 7 12 202 305 16.83 25.42
Realistic 41 6 142 160 11.83 13.33

The Sav m/43 is based on the chassis of the Strv m/41 and thus has a similar level of mobility. It is considerably heavier, however, and thus correspondingly more sluggish. While the forward top speed is adequate, the reverse speed is quite poor, making it hard to retreat.

Armaments

Main armament

Main article: Kan m/44 (105 mm)

The 1946 model of the Sav m/43 now features the 10,5 cm kan m/44, a 105 mm howitzer. It starts off with the very inadequate slpprj m/44 APBC round. This round lacks the penetration or post-penetration damage to be competitive against the tanks the Sav m/43 faces; thus, it is of the utmost importance that the psgr m/49 HEAT shell is unlocked as soon as possible. This round has an amazing 240 mm of penetration, the most of any round available to any Rank II tank in the game, and also has substantial post-penetration effects. There is also an HE round available that is effective against light vehicles and armour.

The shells all have a relatively low muzzle velocity, and it can therefore be quite hard to hit moving targets at long range. Conversely, the substantial arc of the shell trajectories due to the low-velocity shells allows the Sav m/43 to sometimes hit targets hiding behind cover, or to fire from behind cover itself.

The heavier shells also result in a relatively long loading time compared to the 1944 model's 75 mm field gun.

Usage in battles

Like the preceding 1944 model, the Sav m/43 (1946) performs best in hull down positions, as it can use the gun depression to present a steeper angle on the frontal armour to increase its effective thickness. However, it commonly faces tougher opposition at this BR, including the very common T-34, M4A1, and Pz.IV F2 medium tanks, thus the armour should not be depended on in a slugging match against these tanks.

Conversely, the 240 mm penetration on the HEAT round is capable of dealing with anything the Sav m/43 can encounter, even the heaviest of tanks. Hitting accurately with the low velocity shells will take practice, but since HEAT shells do not lose penetration with distance, the Sav m/43 is capable of crippling or destroying even the heaviest tanks at long range.

The side and rear armour is very thin (10-15 mm), and is very vulnerable to even heavy machine gun and autocannon fire. Exposing it to the enemy will lead to a quick demise, especially against the extremely common .50 cal M2 heavy machine gun found on a lot of American tanks.
