What is considered the first part of our Army?

The correct answer is the Continental Army, as it represents the first organized military force of the United States and is foundational to the Army's history. Established during the American Revolutionary War in 1775, the Continental Army was formed by the Second Continental Congress to coordinate the military efforts of the thirteen colonies against British rule. This army set the precedent for the formation of military organizations in the U.S. and eventually led to the establishment of the current Army structure.

In contrast, the Army National Guard is a reserve component that plays a crucial role in the overall defense strategy but was not the first part of the Army. The Marine Corps, founded in 1775, operates independently from the Army and serves specific functions, particularly within naval operations, and thus does not represent the Army itself. The Regular Army, which refers to the full-time professional component of the United States Army, was established after the Revolutionary War and is a continuation of the military legacy that began with the Continental Army.

Understanding the role and history of the Continental Army is essential for grasping the evolution of the U.S. military and its significance in American history.
