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.
The age of enlisting in the armed services should be 19 or 20, because at that age people are more likely to make a better decision about which path they want their life to take. This would also give them a feel for college and a chance to judge whether their life is turning out the way they want it to turn out.
