F-22 76.2mm Field Gun / Anti Tank Gun
The F-22 was a 76.2mm Soviet Field Gun introduced in 1936. The gun was a semi-universal divisional gun also used in a limited capacity as an anti aircraft gun. In 1941/42 the Wehrmacht had captured hundreds of F-22 and they were pressed into service as field guns designated FK 596(r). However, by late 1941 it was decided to rebuild the weapon as an Anti Tank Gun 7.62cm Pak 36(r) and 560 of these were produced some of which were used to arm Marder II and Marder III tank destroyers.
