My father definately fell into that category, although his Army service continued post war with a 12 month tour in Palestine in '46/47 and Z Reserve status into the early 50's which included a return to uniform for a 2-week refresher camp during the Korean War.
However, give him a No.4 and his eyes light up if he could drill with it.........even into his early 70's he could still do a perfect rifle drill routine with a No.4
Have many happy memories from the late 1970's of being in the amusing company of one of Dad's fellow Met Dog Handler's who was ex-22.
