Enlisted age requirements
To enlist in the Thailand military, you must be at least 21 years old and no older than 21 at the time of enlistment. Mandatory call-up at age 21 for Thai male citizens. Reservist liability continues to age 30. Voluntary enlistment earlier (18+).
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). If you are near or over the published maximum, contact a recruiter directly to ask whether a waiver is available for your specific qualifications. Waivers are exception, not rule.
