The work started in February 1944, and the first prototype of SU-100, called 'Object 138', was built in March. Gorlitskiy, chief designer of all medium Soviet self-propelled guns. The development was conducted under supervision of L. This was quite capable of defeating any German tank in service, for which Soviet soldiers gave it the obscene nickname 'Pizdets vsemu' ('Fucking end to anything'). 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). It was designed and built at the UZTM (Russian abbreviature УЗТМ for Уральский Завод Тяжелого Машиностроения - Ural Heavy Machinery Factory, also called Uralmash) in Yekaterinburg. 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 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. The tracks then engine should be next to improve acceleration and manoeuvrability.However, whether you research it before the tracks and engine is up to you. It's no longer optional to research the 122mm D-2-5S if you want to unlock the SU-152.Next go for the 100mm gun as its penetration gives this tank the edge.The radio and 85MM D5S-85BM carry over from the SU-85, so mount those immediately.Overall it is an excellent but tricky tank to master. The SU-100 also benefits from good camo, so it can do both roles without the enemy noticing. However its slow aim time and long reload means that after a shot it must find cover. The 122mm is suited for ambushes, surprise attacks, and supporting your allies on a push to the enemy base. The 100mm is more suited for true 'Tank Destroyer' sniping with a good aim time, decent reload, and acceptable accuracy. The choice of higher DPM on the D10S or higher alpha damage on the D-2-5S allows for different styles of play. However this TD has the biggest punch of its tier, capable of crippling or outright destroying any tank it faces. Most tanks your tier and above won't have to aim for weak spots to damage you. Its thin armor and low hit points (even for a TD) means it cannot and will not take much punishment before becoming a smoking wreck. Vulnerable to drowning when crossing rivers due to low height Rather sluggish acceleration & traverse: turns like a boat Low view range, though still a gigantic improvement over SU-85 Very weak Ammo rack can be hit from the front

122 mm gun can one-shot every tier 4 tank, every SPG up to tier 7 and almost every tier 5 TD (except the AT 2 unless) The 122 mm D-2-5S offers the second highest alpha damage of all tier 6 TDs, only SU-100Y has better

Good choice of guns for different play styles
