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.
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.

In the United States Air Force, the maximum age allowed to enlist and ship to basic training is 27 years old. In the Air Force Reserves, the maximum age is 34 years old. In the Air National Guard, the maximum age is 39 years old. In the United States Navy, the maximum age allowed to enlist and ship to basic training is 34 years old.
