In 1915 Britain acquired a number of "autocanon de 75 mm mle 1913" anti-aircraft guns, as a stopgap measure while it developed its own anti-aircraft alternatives.
During World War II, the British also received the American half-track M3 Gun Motor Carriage under Lend Lease terms and used these in Italy and Northern Europe until the end of the war as fire support vehicles in Armored Car Regiments.
