The 75mm Model 1917 (US) was an American variant of the British 18 Pounder. It used a smaller 75mm bore which accepted standardized French 75mm ammunition.
When the United States entered World War I, it needed more equipment, and there was no time to build new weaponry. The US used Allied weapons, with the French 75mm gun becoming the standard US divisional gun.
Made as a stopgap until French artillery was available, the 75mm Model 1917 US only saw action after WW1 ended. During WW2, allies upgraded this gun with pneumatic tires. The British Army used the 75mm Model for training, and the Finnish Army used them in combat against the Soviet Union.
