In battle school I had the joy of lugging around the C2 which was so old every time you went to fire it on auto the breach block and carrier flew over my shoulder. It was allot easier to shout "bang, bang , bang". In the Bn I had an C1 which I bartered for the skills of a old time British weapons tech to look over. Breaking dinner plates at eight hundred with open sights nine out of ten times. Fought tooth and nail to keep it, they kept trying to give me a SMG. On a couple of excursion with the other branch of service in Victoria they used seamen with C1's as shark patrol when in the warm climates.
