Additional Requirements

When considering joining the army, potential recruits should also consider:

  1. High school diploma or equivalent

  4. Citizenship or permanent residency

Waivers and Exceptions

"Age waivers may be granted on a case-by-case basis, particularly for individuals with specialized skills or prior service." - Department of Defense Instruction 1304.26

Some age requirements can be waived under specific circumstances. For example, the US Army's Age Waiver Policy allows for waivers to be granted for individuals up to 42 years old for certain roles.

Career Impact and Retirement

Age at enlistment affects retirement timing:

Retirement Years = 20 years of service
Pension = 50% of base pay
Early retirement available after 15 years in some cases
