Hello all. I'd like your advice on whether there is any way I can join the army as an officer. I am 29 years 2 months! The Army Careers Office has informed me I am too old to apply, and the website states "as a general ruleâ¦candidates should beâ¦under 29 on entry to Sandhurst" however other literature more vaguely mentions encountering difficulties applying from late 20s/early 30s. Can anyone tell me who ultimately decides eligibility? Is it in the legislation? Can cap-badges choose to be more flexible? Or would it depend on Sandhurstâs entry criteria? Thanks.
