Answer: The Continental Army of the thirteen British colonies in North America.
Explanation: The United States found it more difficult to fight against their own men during the Revolution because Great Britain had American colonists called leists who were loyal to the English Crown and who fought against their own countrymen arming against the Revolution, which caused a great disadvantage to American settlers compared to the English army, since it is a situation that was not expected.
The United States began to provide significant military supplies and other assistance to the Allies in September 1940, even though the United States did not enter the war until December 1941.
