After the end of World War Two the Romanian army began to build their first armoured units. They sought help from the French to assemble a battalion of Renault FT-17 light tanks. These units developed in the 1930s to include not only French but Czechoslovakian designs. As the war progressed the Romanian military adopted captured Russian ordnance to arm their vehicles, the first such merger was to arm the now obsolete Renault tanks with Soviet 45mm anti-tank guns. Another more potent weapon was used to build the Tacams, these tank destroyers mounted a 76mm Russian field gun.
