Their battlefield success contributed to an Allied victory. The doughboys' efforts on the battlefields of Europe were crucial to the Allied cause. They played significant roles in important engagements such as the Meuse-Argonne Offensive, which forced the German Army into retreat. Their tenacity, courage, and adaptability in challenging combat situations helped turn the tide in the Allies' favor, leading to the eventual armistice and Germany's defeat.
Their experiences helped shape policies related to veterans. The experiences of the doughboys upon their return home led to significant changes in the way the United States treated its veterans. The government recognized the need for better support for those who had fought in the war and enacted benefits and programs to assist them, including the creation of the Veterans Administration and financial support for disabled veterans. These policies, shaped by the challenges faced by the doughboys after their service, laid the foundation for future initiatives to support and care for veterans.
