To do that, several things need to be looked at, like: what type of relationship there is between the person being abused or harassed and the person doing the abuse/harassment; the age of the person being abused or harassed; and the type of abuse or harassment.
For the Army, the maximum age is 35. For the Navy, age waivers start at 34-years-old. For the Air Force, the maximum age allowed to join is 39-years-old. The Marines have the lowest maximum age for regular military service at 28-years-old.
The Army has raised the enlistment age to 42 (for Active Duty, Reserves, and Army National Guard), made possible under provisions of the Fiscal Year 2006 National Defense Authorization Act.
