As of 2014, the U.S. Army employs more than 675,000 soldiers consisting of both active duty and reserve personnel. Each branch of the military has standard enlistment requirements regarding age. The Army requires that applicants be at least 17 years of age but not more than 35 at the time of enlistment.

In 2006, the U.S. Army raised the age limit for first-time recruits from 35 to 42 in order to increase the number of Army personnel fighting in the Middle East. The maximum enlistment age was lowered back down to age 35 in 2011, as the Army had satisfied its increased recruiting needs.
