SD2:M18 Hellcat

 is a United States Anti-tank unit in Steel Division II.

Background
In 1941, The US Ordnance department called for the design of a fast tank destroyer armed with the 37mm gun, in accordance with US tank destroyer doctrine. This was later changed to the British 6-pdr gun and after that to the 76mm M1 Gun. Production started in July 1943 and ceased in October 1944, with around 2500 Hellcats manufactured in total.

To attain the Hellcat's legendary speed, armour had to be sacrificed and this made the tank destroyer vulnerable to most German AT weapons. Its open-top compartment (also found in the Wolverine design and other US tank destroyers) further added to its vulnerability. While its speed was not often used in combat, Hellcat crews did have a tactical advantage as they could outflank heavy tanks and land a flank or rear shot. Its 76mm gun struggled against the front of Tiger and Panther tanks unless it used the rare HVAP ammunition.

Despite all these flaws, the M18 Hellcat was the most effective American tank destroyer of World War II and had a higher kill to loss ratio than any tank or tank destroyer fielded by American forces in World War II. Prototypes of the tank first saw battle in Italy, but they mainly gained lasting fame for their combat performance in the Northwest Europe theatre.

During the battle for Brest, 2nd Infantry (SD2) had Company B, 705th Tank Destroyer Battalion attached.
