Minimum 17 (parental consent if under 18). Upper limit effectively 57 — must complete Initial Minimum Period of Service before age 60.
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).
