the backward movement (displacement) of an artillery gun or just its barrel after being fired, caused by a rebound.
Old guns (until the late 19th century), whose barrels were rigidly fixed to the carriages, rolled backward after being fired. The idea of a flexible connection between the barrel and the carriage was first proposed and carried out in practice by the Russian designer V. S. Baranovskii in 1872. In present-day guns, which have a flexible connection between the barrel and the carriage in the form of antirecoil devices, only the barrel recoils. This provides gun stability during firing, the maximum rate of fire, and accuracy of hits.
