In the United States Army, Army Reserves, and Army National Guard, the maximum age allowed to enlist and ship to basic training is 35 years old. The Army experimented for quite some time allowing anyone up to the age of 42 years old to enlist and complete basic training. On April 1st, 2011, they reverted this to the lower age limit.
To join the Army Reserve, you must be a U.S. citizen or a resident alien between the ages of 17 and 27. Seventeen-year olds need parental consent. You must have a high school diploma, and have no more than two dependents.
