In 1935, the reconnaissance battalions of the Red Army received the first 76mm »dynamo-reactive« guns designed by L.V.Kurchevskiy.
The recoilless gun was only one in a range of calibers reaching from 37 to 305mm and produced by the thousands in the 1930s.
In order to improve mobility, the chassis of the GAZ-A staff car was lengthened by one axle resulting in a 6x4 light truck and named »GAZ-TK«, the »T« for triaxal and the »K« for Kurchevskiy.
However, the Kurchevskiy guns showed so many deficiencies in service that their designer fell victim to the Stalin purges of 1937.
The further 21 samples probably never saw service in the upcoming Great Patriotic War due to mechanical failures.
