Military Age Limit: Maximum Enlistment Age by Service
When we checked on November 2, 2026, each service site stated its own enlistment age limit: 42 on goarmy.com, before the 42nd birthday on airforce.com, 41 for enlisted programs on navy.com and 28 on marines.com. Federal law lets the Secretary concerned accept original enlistments in the Regular components of persons from 17 to 42 years of age (10 U.S.C. 505(a)). The table and quotations below give each page's exact words, and the ASVAB scores page and the Army cutoff scores page cover the test side.

What the statute says
“The Secretary concerned may accept original enlistments in the Regular Army, Regular Navy, Regular Air Force, Regular Marine Corps, or Regular Coast Guard, as the case may be, of qualified, effective, and able-bodied persons who are not less than seventeen years of age nor more than forty-two years of age. However, no person under eighteen years of age may be originally enlisted without the written consent of his parent or guardian, if he has a parent or guardian entitled to his custody and control.”
When we checked on November 2, 2026, uscode.house.gov said its text contained the laws in effect through Public Law 119-136 (October 22, 2026).
