Age Limit for Enlisting in the US Military?

I'm a high school junior considering a future in the military. I'm curious about the age restrictions. What's the maximum age for enlisting in the US military? Are there different limits for different branches?

Each branch of the United States Military has its age regulations which may vary. Generally, the limits are as follows:

1. Army: 17 to 35 years

2. Navy: 17 to 41 years

3. Air Force: 17 to 42 years

4. Marine Corps: 17 to 28 years

5. Coast Guard: 17 to 41 years

6. Space Force: As a department of the Air Force, it likely follows the same age restrictions, however, specific information is difficult to come by since it's a newer branch.

The age limits mentioned are for active duty enlistments. There might be some flexibility for reserve or prior service applicants. Keep in mind that these are the maximum ages for enlistment itself; officer programs and other advanced roles, such as military healthcare, tend to have different and sometimes older age maximums.

Also, all branches require that you be at least 17 years old to enlist, but all require parental consent if you're under 18. The maximum age means you must enlist and ship out to basic training before your 35-40th birthday depending on the branch.

These are general guidelines so it's always best to confirm with a recruiter as certain mitigation circumstances may sometimes alter these limits. I hope this helps and best of luck with your decision.
