The Lorraine 155 Mle.50 has very little armour (although some are sloped enough to deflect certain low-rank rounds), and can generally be penetrated by most guns of its rank. Even worse, however, the 'casemate' (if it can even be called that) has very little armour, and in some places can be shot through with machine guns. The machine-gunner (operating the 151) is completely open to the elements. Generally, you want to rely on good map placement and mobility, rather than armour.

Against most opponents, the M551 can be destroyed with a single shot. It's best to just stay in one spot along a road and wait for an enemy to pass by where so that they present their vulnerable side armour and vitals to target at. Once the ATGMS are unlocked then the player can stay out of range from everything but ATGMs.

The best method of using the large-calibre weapon on the Loraine is to exploit the high-explosive power against thin-armour on the enemy. Like other large calibre HE tanks, shooting below an enemy vehicle will penetrate its belly armor. This is an effective, albeit difficult way to engage tanks whose armor is greater than what your HE shell can penetrate.
 +
 
 +
Some targets to keep in mind of, and their weak points:
 +
 
 +
* Tiger I - While seemingly a hard enemy to face, the Tiger is easily dispatched with a side shot. A hit to the roadwheels will penetrate the tank, with the shell fragments going through the thin armor on the underside of the tank's sponson. This is also possible to do to Tiger IIs, but usually results in much less damage done.
 +
* Tiger II P, Panthers D and A - a hit to the bottom of the curved turret face of these tanks will cause the HE shell to pen the roof of the vehicle. This can also be done on tanks with flat turret fronts ( Tiger I, Tiger II H, Panthers G and F) by aiming for the lower half of the turret, but is not as reliable.

The ''Sheridan'', even with the ability to fire ATGMS, is an extremely difficult tank to use due to it having no armour. Even some high-power MGs can penetrate the armour easily. The stock heat round while having high pen drops like a rock at range and bounces ALOT. Immediately upon reaching the tier 2 modifications research the ATGM missiles. Once those are unlocked the ''Sheridan'' becomes a fast and mobile missile platform that out ranges most vehicles in game. With only the stock HEAT always aim for ammo racks. This is pretty much the only way to destroy the heavier tanks. The mobile AAs will be the M551's biggest problems. While the ''Sheridan'' can drive circles around most of its heavy opponents, the fast anti-air turret can keep up with the M551, able to tear the armour to pieces. The ATGMs are a vast improvement over the HEAT rounds, one shotting pretty much everything and extending the ''Sheridan'' range past that of most of its opponents.

−
Stay in the back, everything will one shot the tank. Use the M551's speed and maneuverability to get around enemies. Don't be afraid to get in real close to the enemy, because with only HEAT, the 152 mm's effective range is very limited. Once ATGMs are usable, the ''Sheridan'' becomes an extremely formidable sniper. Able to fire on target, destroy a target, then move position for another opportunity. In Arcade, the ''Sheridan'' is an easy target for everyone, but in realistic and simulator its speed makes it a very hard target to hit.

===Development===
 
−
In the post-war period, U.S. Army specified for a new light tank that is light enough for air-transportation and have a large cruising range. The first resulting light tank, the [[M41A1|M41 ''Walker Bulldog'']], did not meet these specifications and the following development such as the [[T92]] were cancelled after the discovery of the amphibious Soviet [[PT-76B|PT-76]] tank, which added a requirement for the light tank to also be amphibious. A new tank design began development, using aluminum alloy to save weight, a fabric screen for flotation, and a controversial [[M81 (152 mm)|152 mm gun/launcher]] for firepower with the Shillelagh missiles. However, the design's lightweight and mobility made it favorable and so the tank was approved for Army standard in May 1966 and designated the '''M551 ''Sheridan'''''. Between 1966 to 1970, 1,662 ''Sheridans'' were produced at a program cost of $1.3 billion.<ref name="ZalogaM551">Zaloga, 2009</ref>

The ''Sheridan'' first saw service in June 1967 n the 1/63rd Armor Regiment at Fort Riley. The first air usage of the ''Sheridan'' came from the 1/17th Cavalry at Fort Bragg. Its first overseas deployment was to South Korea in November 1968 and Europe in January 1969. 800 ''Sheridans'' were deployed worldwide by 1971. Troubles with the 152 mm Gun/Launcher plagued the M551's early service life as attempts were made to fix the issues in the weapon's ammo propellant and ability to fire missiles.<ref name="ZalogaM551" />

The ''Sheridan's'' tank's first combat would be seen in Vietnam under the urging of General Creighton Abrams. The tank first arrived in January 1969 modified for the environment in a configuration dubbed "Two-Box M551" with many complex mechanical instrument boxes removed (save for two), as well as the ability to fire the Shillelagh missiles disabled and the production of a fletchette ammunition for the 152 mm gun/launcher. First impressions of the ''Sheridan'' were positive due to the weapon's effectiveness in anti-infantry and bunker busting roles, as well as the mobility able to maintain speed with the M113 armoured personnel carriers. However, experience soon soured when the lack of armour became apparent compared to the [[M48A1|M48 Pattons]] employed in the theater, with the M551 vulnerable to mines and the numerous hand-held anti-tank weaponry.<ref name="ZalogaM551" />

Post-Vietnam, the M551 Sheridans underwent a product improvement program (PIP) that upgraded the design. The next combat operation would be in ''Operation Just Cause'' in Panama, featuring the first and only time tanks were parachuted into a combat zone. Inserted with the 82nd Airborne Division, the M551 proved a popular psychological weapon against the opposing forces. After Panama, the M551 were also deployed to Saudi Arabia as part of the Gulf War in both Operation ''Desert Shield'' and ''Desert Storm'', where in the latter they fought Iraqi units equipped with [[T-55A|T-55s]] and [[T-72A|T-72s]] in the only time in the M551's history that the gun-launched Shillelagh missiles were used against an enemy.<ref name="ZalogaM551" />

Back in the United States, the M551 also found use in the U.S. Army's National Training Center at the Mojave desert in California, where they are dressed up to look like Soviet vehicles to play as the "opposing forces" to train the army units on tactics in the battlefield. After the Gulf War, the Sheridan's combat career came to an end and so they remained in service at the National Training Center until 2004. The ''Sheridans'' were retired without any replacement in the airborne tank role. Though attempts had been made in the late 1990's for a replacement, the Army decided that an airborne tank was simply not worth the cost for a specialized vehicle.<ref name="ZalogaM551" />

Description

GarageImage Lorraine 155 Mle.50.jpg


The Lorraine automoteur de 155 mm modèle 1950 (shortened as Lorraine 155 Mle.50) is a gift rank III French tank destroyer with a battle rating of 4.3 (AB/RB/SB). It was introduced in Update 1.77 "Advancing Storm" during the 2018 WW2 Chronicles.

General info

Survivability and armour

The Lorraine 155 Mle.50 has very little armour (although some are sloped enough to deflect certain low-rank rounds), and can generally be penetrated by most guns of its rank. Even worse, however, the 'casemate' (if it can even be called that) has very little armour, and in some places can be shot through with machine guns. The machine-gunner (operating the 151) is completely open to the elements. Generally, you want to rely on good map placement and mobility, rather than armour.

Armour type:

  • Rolled homogeneous armour
  • Structural steel
Armour Front (Slope angle) Sides Rear Roof
Hull 16 mm (70°) Front glacis
16 mm (2-73°) Transmission housing 		16 mm 10 mm (0-42°) 10 mm

Notes:

  • Suspension wheels are 10 mm thick while tracks, sprocket wheels, torsion bars, and return rollers are 20 mm thick.
  • Belly armour is 10 mm thick.
  • Gun breech is 300mm thick, while the barrel itself is 25mm.
  • Gun carriage around the gun is 20mm thick, while the gun mount/traverse device is 40mm thick.

Usage in battles

The best method of using the large-calibre weapon on the Loraine is to exploit the high-explosive power against thin-armour on the enemy. Like other large calibre HE tanks, shooting below an enemy vehicle will penetrate its belly armor. This is an effective, albeit difficult way to engage tanks whose armor is greater than what your HE shell can penetrate.

Some targets to keep in mind of, and their weak points:

  • Tiger I - While seemingly a hard enemy to face, the Tiger is easily dispatched with a side shot. A hit to the roadwheels will penetrate the tank, with the shell fragments going through the thin armor on the underside of the tank's sponson. This is also possible to do to Tiger IIs, but usually results in much less damage done.
  • Tiger II P, Panthers D and A - a hit to the bottom of the curved turret face of these tanks will cause the HE shell to pen the roof of the vehicle. This can also be done on tanks with flat turret fronts ( Tiger I, Tiger II H, Panthers G and F) by aiming for the lower half of the turret, but is not as reliable.

Pros and cons

Pros:

  • Powerful 155mm gun with a HE shell on-par with the KV-2's gun
  • Pintle-mounted 20mm cannon that is deadly to lightly-armoured vehicles and aircraft
  • Decent mobility
  • Good reverse speed

Cons:

  • Thin armor with an open casemate, allows even rifle-calibre rounds to affect the crew
  • Despite thin armor, it's thick enough to trigger most fuses in APHE shells
  • Large profile
  • Long reload time; increases if the loader is taken out
  • If the machine-gunner is knocked out, so is the ability to use the 20mm cannon
  • No AP shells, only HE shells
  • Bad gun depression of 5°

History

Prototypes of the Lorraine 155 Mle.50 passed trials in 1950, but never reached production.
