The United States Army, founded in 1775 as the Continental Army, serves as the land-based component of the U.S. Armed Forces, charged with safeguarding national interests through terrestrial operations. From its beginnings in the Revolutionary War to contemporary modernizations, it has transitioned from a frontier force into a technologically sophisticated military. Writers such as William T.
Sherman emphasized its organized structure during peacetime, while Kelly Miller focused on its incorporation of reserves and the National Guard. The 115th Congress acknowledged its evolution into a force capable of modern warfare. These viewpoints highlight the Army’s lasting role as a fundamental pillar of U.S. military strength, adjusting to historical and strategic needs while preserving its central objective of land superiority.
