Marines vs. Army: Definition and Origins


The Marines originated as specialized infantry onboard naval vessels, with a focus on ship-to-ship combat and amphibious warfare. Their creation dates back to the 17th century but varies by country. In the United States, the Marine Corps was founded on November 10, 1775, initially as Continental Marines during the Revolutionary War. They operate under the Department of the Navy and are known for being a rapid-response force, capable of deploying quickly for combat and humanitarian missions.


The Army, on the other hand, is the main ground-based military force and usually one of the oldest branches of a nation’s armed forces. The U.S. Army was established on June 14, 1775, predating the Declaration of Independence. It is the largest and oldest established branch of the military, falling under the Department of the Army. The primary mission of the Army is to engage in prolonged land campaigns, conventional warfare, and peacekeeping operations.

  • Army: It serves as the main ground-force of the United States and is capable of a wide range of military operations, from humanitarian missions to full-scale combat.


  • USMC: We manage a much smaller force compared to the Army, making our operations more focused.
  • Army: The Army is the largest branch of the U.S. military, which allows it to undertake extensive and sustained land missions.


  • USMC: We undergo initial training that includes 13 weeks of Boot Camp, followed by School of Infantry for combat roles or other specialized schools.
  • Army: Soldiers receive 10 weeks of Basic Combat Training and then proceed to Advanced Individual Training in their respective fields.

Operational Structure:

  • USMC: Our operational units are often smaller, such as the Marine Expeditionary Units (MEUs) designed for quick deployment.
  • Army: Army brigades and divisions are larger and have more heavy equipment, which provides greater firepower but may result in slower deployment.
