The Type 94 37mm AT guns were typically assigned in groups of four to combat infantry regiments.
Each weapon was manned by a squad of 11 personnel, and was kept in contact with the regimental headquarters (typically up to 300 meters away) by field telephone or messenger runners.
With the standard AP shell, it could penetrate 1.7 inches (43 mm) of armor at 500 yards (460 meters).
The Army Technical Bureau continued to experiment with ways to increase muzzle velocity through 1941.

The Type 94 37mm AT gun was effective against Soviet lightly armored BT tanks in the Nomonhan Incident of 1939, but was considered obsolete against more advanced Allied tanks, such as the M4 Sherman, by the start of the Pacific War.
However, it remained in service on most fronts in World War II for lack of a better replacement.
 The Type 1 47 mm Anti-Tank Gun was put into service starting in early 1942, and was intended to replace it, but was never available in large enough numbers to do so completely.
