The 37mm 61-K was originally developed in the late 1930's, and used extensively on the Eastern Front by the Red Army against the dive bombers and other low-to-medium-altitude aircraft of the Luftwaffe.
Its high muzzle velocity and rate of fire meant that it was just as effective against ground targets, such as lightly armored vehicles, as it was aircraft.
During the post-war years, the 37mm 61-K saw service with many countries outside the Soviet Union, including those in Africa and the Middle East, including the army of the United Arab Republic during the Six-Day War.
