 Maximal, horse-drawn, transport speed was only 6–7 km/h.This limited the anti-tank effectiveness of the M1902/30 and essentially rendered the gun obsolete in swift and maneuver warfare, so it was phased out of production in 1937 when the new divisional gun, the F-22, was adopted.By 1 June 1941 the RKKA possessed 2,066 M1902 and 2,411 M1902/30 guns.
