The USSR SU-100 anti tank 1944

SU-100 accompanies T-34-85 of the 1st gds tank army in the outskirts of berlin.

The SU-100 was a Soviet tank destroyer. It was used extensively during the last year of World War II and saw service for many years afterwards with the armies of Soviet allies around the world.

It was developed in 1944 as an improvement to the SU-85, built on the same chassis as the T-34-85 tank. It was designed and built at the UZTM (Ural Heavy Machinery Factory, also called Uralmash) in Yekaterinburg. The SU-100 quickly proved itself to be among the best self-propelled anti-tank guns of World War II, able to penetrate 125 mm (4.9 in) of vertical armor from a range of 2,000 m (1.2 mi) and the sloped 85 mm (3.3 in) front armor of the German Panther from 1,500 m (0.93 mi). This was quite capable of defeating the frontal arc of any German tank in service with the exception of the King Tiger, for which Soviet soldiers gave it the nickname "Pizdets vsemu" ("It's curtains for everything").
