I would hesitate to cite Hong Kong without a lot of detailed research. Closer to home, our individual training system poise-unification was badly screwed up. At one stage small arms were not issued or taught, and with a viable internal security threat, the "land element" was tasked to protect the other elements' bases, etc. In Shilo at the school the TQ3 wing (old RCA Depot) taught GMT, but this eventually was cut.
After the FLQ Crisis of 1970 SA, etc was reintroduced, but not with a lot of enthusiasm. The emphasis seemed to lean towards manning drop in centres, etc, and leave was an afterthought. On paper, troops were supposed to get two weeks annual in the summer, but this was not taken seriously. Personal example, in 1973 I took over D Bty in May, went on practice camp, and then went to Italy for an attachment to the IT Mountain Artillery, still using mules. After that a brigade exercise in Pet, a break for leave, another practice camp, then off to Norway for mountain shooting and a FTX with Brigade Nord. Back to Pet for another practice camp, then three months of support to trials, with weekends with Ontario reserve arty regiments. From Labour Day to St Barbara's Day, I had one day off, though I was able to get the troops about a free weekend per month, and my BSM paralleled my situation.
This was a bit unusual, but not that much. There was a lot of blind eye turning higher up the chain, and not that high. Oh, and no accumulation authorized in those days. There was a later attempt to fix it, but the damage had been done. Now, no HHTs or moving grants or whatever, very, very slow promotions in gunner land that lasted five years or more, and one grieved for the screwing our troops were getting. Somehow, they stuck it out and excelled i[n the field.
