The key is to also understanding that most trades and even line serials inside certain trades have different requirements.
The Ligth Infantry role has different requirements than LAV based Infantry - who have different requirements than the Leo2 crews, who have different requirements than the Gunners, - and the gunner trade has many different requirements due to gun line (towed or SPA) or FOO (Light or LAV) etc.
Of course its easier just to try to jam everyone in a arctic tent...
But snarky and sarcastic comments aside - for years there haven't been proper solutions to a variety of REQUIREMENTS.
7.62mm belt carriage for dismounted use? I mean that isn't an unknown issue - the whole just carry the metal can isn't an appropriate answer.
The C6 got fielded to the Infantry in what 1986 ish?, I know Gagetown had them in 1988 at the School.
It is 40 years...
Not exactly sure how this issue wasn't ever addressed - outside of Troops buying their own bags/pouches.
