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 Army raised the active-duty age limit to 40 in January as an interim step while it worked out the additional medical screening requirements for recruits ages 40 to 42. Before January, an applicant could not have reached his or her 35th birthday. The Army Reserve age limit was raised from 35 to 40 in March 2005.
