These extensions often got in the way of fitting The M36B1 had the hull armor configuration of the late production M4A3 Sherman tank. The sides and rear of the upper hull featured angled extensions or covers over the upper run of track. Dedicated anti-tank vehicles made their first major appearance in the Second World War as combatants developed effective armored vehicles and tactics. As it was found that the M10 tank destroyer had struggled against German tanks like the The supply of M10A1s eventually ran out, so it was decided in January 1945 that M10 hulls would be used for all further conversions. The rear was 1.75 to 5 in (44 to 127 mm) thick. The M36 initially retained the M10A1's "stirrup" gun rest on the rear hull; crews were unhappy about the lack of a proper travel lock for the 90 mm gun, and many improvised their own from travel locks taken from tanks. An example of the development of tank destroyer technology throughout the war are the Marder III and Jagdpanzer 38vehicle, that were very different in spite of being based on the same chassis: Marde… This meant that the driver normally had to turn the entire tank onto its target, a much slower process than simply rotating a powered turret.The most famous Italian tank destroyer of the Second World War was technically not a tank destroyer, but self-propelled artillery. The The closest the British came to developing an armored tank destroyer in the vein of the German Jagdpanzers or Soviet ISU series was the Churchill 3-inch Gun Carrier—a During World War 2, the Romanians made some tank destroyers by removing the turrets of some of their tanks and adding a compartment and a stronger gun that could face the new Soviet tanks that were much stronger than the Romanian ones. American Locomotive Company converted 672 M10 hulls into the The first 40 M36s did not make it overseas until September 1944, and entered combat in October 1944. A proper folding travel lock better-suited to the 90 mm gun was added to the rear hull at about this time. Such designs were also easier and faster to manufacture and offered good crew protection from artillery fire and shell splinters. In reality, German attacks effectively used British tanks in the early years of the war, both infantry and cruiser, were (with the exception of the pre-war Matilda I design) equipped with a gun capable of use against contemporary enemy tanks—the 40 mm The self-propelled guns that were built in the "tank destroyer" mould came about through the desire to field the QF 17 pounder anti-tank gun and simultaneous lack of suitable standard tanks to carry it. Some were little more than stopgap solutions, mounting an anti-tank gun on a tracked vehicle to give mobility, while others were more sophisticated designs.

The sides and rear of the upper hull were 0.75 in (19 mm) thick, sloped at 38 degrees from the vertical. The rounded cast gun shield was 3 in (76 mm) thick. As a result, they were of a somewhat extemporized nature. Ninety-one units were built in 1943 under the name Ferdinand, after its designer Ferdinand Porsche, using tank hulls produced for the Tiger I tank design abandoned in favour of a Henschel design.. The top was 0.38 to 1 in (9.7 to 25.4 mm) thick, and the sides were 1.25 in (32 mm) thick. General Andrew Bruce criticized the M36 due to it being too slow.The lower hull had 1 in (25 mm) thick armor on the sides and rear. As the massive muzzle blast of the 90 mm gun obscured the crew's vision and reduced the rate of fire, a double-baffle muzzle brake was fitted to all vehicles after the first 600, beginning in early November 1944. However, the lack of a rotating turret limited the gun's traverse to a few degrees. The sides of the M36's rounded turret were 1.25 in (32 mm) thick, constructed of rolled armor plate. Mounting the gun on the In 1942 the General Staff agreed on investigating self-propelled mountings of the 6-pounder, 17-pounder, While there was a general move to a general purpose gun that was usable against both tanks and in supporting infantry, there was a need to put the 17 pdr into a tank for use against the enemy's heavy tanks. The requirement was later increased to 600 vehicles on May 15, 1944. Jun 21, 2019. On the following day the battalion beached on Utah Beach, Normandy coast, France. The First and Ninth US Armies used M36s to reequip tank destroyer battalions attached to armored divisions.
