Looking for some information regarding commissioning from enlisted ranks. Yesterday I had my interview with the Sergeant Major who tried to persuade me to go down the officer route. However Iâm desperate to join the army and enlisted would be my quickest option (already taken 3 months due to various interviews, medical and pre-selection). Whatâs the minimum/average time an enlisted soldier showing officer material would serve before they would be put forward for a commission? Currently my first choice is Int. and second RMP.
