Dragging sand bags is a casualty extraction - believe it or not in major combat operations the RCAF could take casualties, or alternatively any number of vehicle or work place accidents can occur in which you ought to be able to move your fellow aviator to safety.
Similarly the dashes, not sure how you got ducking out of that but we shall carry on, reflect the ability to move to cover. We had RCAF pers on KAF when it got attacked, including by ground forces, I presume we want those personnel to be fit enough to seek cover.
Sand bag pick up are about loading stores… like I dunno ammunition or other heavy stores. I’m assuming AVN techs do that? Or anyone does that when they get resupplied.
Do we need to keep going or have we arrived at a point where you can stop jumping topic to topic and being wrong each time?
