American 3" Anti Tank Gun and Crew
By 1943 the American Army realised it needed a much heavier anti tank guns in order to deal with the increasingly well armoured German tanks appearing on the battleground.
As with most other armies in WW 2 the answer was found in modifying existing AA guns. The new gun arrived in the European theatre in late 1944 in time for the Battle of the Bulge.
