Foreign guns: 5812 English 42mm AT guns were received from Great Britain in 1941-42. they were used in Anti-Tank Artillery formations. In 1939-40 in Poland and Baltic countries there were captured several dozens of Bofors 37mm AT guns. There are no data about their usage, but it's obvious that they were utilized due to lack of AT guns in RKKA in that period. [3]
