That's going back a ways - FN C1 A1 - helluva a satisfying kick to those.
Lighter toys in my short time were the Stirling SMG and 9mm Browning.
Heavier was the old John Wayne stuff: .30 and .50 Brownings, Carl Gustav, M74 LAWS, etc. Driving a Lynx full time on a two week exercise, deuce & 1/2, 3/4
Looking back and comparing with guys in other regiments, apparently armored reconnaisance reserves were exposed to a varied education (or the others forgot half of what they were taught by the time I asked them). I was always conscious of the fact guys my age south of the border were doing it for real in Vietnam and I was playing silly bugger on weekends.
