When I first joined the main ad - posters in buses, etc, were the big thing - showed two guys (PPCLI, actually) with a Bren gun. The words said: "A career with a future."
I joined and learned, shortly afterwards that my future was, indeed, as the section 2I/C (in the exalted 'rank' of LCpl) with a C2 (which was only very slightly lighter than the Bren) and my mate, a fellow named Montcrief from the Nort’ Shore of NB, the human pack mule. We never got a chance, as the old song Movin' on said to practice, à la the late Cpl. C.O. (Punchy) Bell, playing Bren gun boogie on a Chinaman's back, but we had fun anyway.
The Navy ad said "Go places! Go Navy!" It seemed interesting, I almost joined until I saw the poster in the recruiting office with two guys (who I learned, later, were NOT in The RCR) standing in front of a Ferret scout car which was parked beneath some palm trees. That was the Army I wanted to join - but London, Ipperwash, Meaford, Petawawa, Gagetown, and, and, and ... beckoned … I got to see a few palm trees and a chum in C/8CH let me drive a Ferret back about 40 years ago, which was great fun.
Ahhhh, memories.
