Who provided weapons for the first American units? Answer: The first American units were provided weapons by various sources, including European allies and domestic manufacturers. During the American Revolutionary War, France became a crucial ally to the American forces and provided them with weapons, ammunition, and other supplies. In addition, American soldiers used weapons manufactured domestically, such as the famous Pennsylvania rifle. The adoption of standard weapons for the U.S. Army began with the establishment of the Springfield Armory in 1794, which was responsible for producing weapons like the M1816 musket.
