Answer:
Doughboys
Step-by-step explanation:
American soldiers in World War 1 were commonly referred to as "doughboys". The exact origin of the term is unclear, but it is believed to have derived from the white belts that American soldiers wore as part of their uniforms, which were said to resemble the flour-covered aprons of cooks, or "doughboys," in kitchens and bakeries. The term became widely used during World War 1 and was adopted as a nickname for American soldiers in subsequent conflicts as well.
