Junior Entry from 16 with parental consent; Senior Entry from 17.5. Officer entry typically must complete RMAS before 29. Some specialist roles have higher upper limits.
Officer commissioning age limits
Officer candidates must typically be between 18 and 29 years old. Different commissioning paths (academy, OCS-equivalent, direct commission for specialists) often have their own age windows — confirm with the official recruiting authority.
What about waivers and exceptions?
Most militaries publish hard age cutoffs but maintain limited waiver authority for critical specialties (medical, legal, chaplaincy, technical skill imports).
