U.S. Army by the numbers

  • U.S. Army by the numbers

    From the United States Army's inception in the Revolutionary War to its 244th birthday June 14, this branch our nation's military has served on the front line as America has gone to battle domestically and on foreign soil. At the same time, the Army has made its mark as arguably the most powerful military organization ever to march in step and made untold contributions to the culture and history of the republic.

    Even with its long history and commitment to tradition, the Army has gone through numerous evolutions, particularly with its demographics. The Army is now incredibly diverse, with a healthy number of minorities and women in the enlisted and officer ranks. It also has a rich political history, as out of its ranks have come presidents, senators, and representatives. The Army is a significant force in education, as well: from its service academy at West Point to ROTC and JROTC programs to offering benefits to help veterans pay for college or enabling others to pursue higher learning credits who might otherwise not be able to afford it.

    On the 244th anniversary of the U.S. Army, Stacker takes a close look at the history, trends, demographics, fun facts, and culture that have made the military branch what it is today.
