I have been up here in meaford teaching for the last few months on reseve BMQ-L's. There is no standard within brigades, or even sometimes units as to scale of issue. I have seen 3 different candidates from the same unit, one with a UAB(mob box), one with a barracks box, and one with neither. So i think it is all dependent on who does your initial issue, and what is currently available at the ASU/local base doing your kitting.
Now, about what you are actually entitled to, that is a whole nother matter.
