Leon here - Were you by any chance in the Canadian Princes Pat Regiment?  I was in the US 3rd AAA AW BN, 3rd Inf Div and attached to the Canadian Princes Patricia Regiment for a while in 1951.   I'm not sure but I think it was a Field Artillery Unit and we were attached as protection support.  We had light tanks with twin 40MM guns and halftracks with quad 50 Cal machine guns.  I'm the guy standing by the old 1984, red, white, & blue GMC Pickup with a topper on the back in the "Members section".
