The SU-76 was a Soviet self-propelled gun used during and after World War II. The SU-76 was based on a lengthened and widened version of the T-70 light tank chassis. Its simple construction made it the second most produced Soviet armoured vehicle of World War II, after the T-34 tank.
Crews liked the vehicle for its simplicity, reliability, and ease of use. However, the steering was also sometimes regarded as cumbersome, leading crews to also refer to the vehicle as suka (Russian: сука; "bitch") or suchka (Russian: сучок; "little bitch"). It was also nicknamed Golozhopiy Ferdinand(Russian: Голожопый Фердинанд; "bare-arsed Ferdinand") due to its very light armor and somewhat similar silhouette, when compared to the Germans' heavy Ferdinand/Elefant casemate tank destroyer of some 65 tonnes in weight.
The T-40 amphibious scout tank was an amphibious light tank used by the Soviet Union during World War II. It was armed with one 12.7 mm (0.5 in) DShKmachine gun. It was one of the few tanks that could ford a river without a bridge.
It was primarily intended to equip reconnaissance units. A land-based version of the T-40, the T-40S, was produced, although was later redesignated theT-60. The T-60 was cheaper, simpler, better-armed, and could fulfill most of the same roles, so T-40 production was halted.
The vehicle served mainly in Operation Barbarossa and the defense of Moscow, and it was rarely seen after that point, although it was used in Soviet training schools until 1946. A total 44 examples of the type were later fitted with Katyusha rocket launchers, firing 82 mm unguided rockets from a 24-rail launcher. [Source: wikipedia]
