There are technically no specific age requirements for soldiers seeking to become Army Rangers. Thus, the effective age limits are the same as those required to join the Army in the first place. Applicants must be at least 17 years old (or 18 without parental permission) and no older than 41 years old.
The earliest age at which individuals can enlist in any branch of the U.S. military is age 17, but at this age, they must have parental consent. However, the average age is higher given that some people enlist later. The maximum age for most branches is 35. On its recruiting website, the U.S. Army reported an average enlistment age of just under 21 in 2012. This was slightly lower than the average age from 2010 and 2011.
