I'm aware of that. It's just that the TU reduction from shooting was quite substential, while the one from walking was not. Must have been right on the edge.
BTW, I just discoverd that during outfitting/deployment the numbers indicating how many items are in a pile vanish if you switch to a player unit that has been spawned for that mission and then switch back to your soldiers.
Case in point would be the "David Vincent" mission in XCF. If during deployment you switch to David Vincent (unit can't access your items, i.e. ground is empty) and then switch forward/backward to your units the items on the ground are missing the numerical indicators. They only reappear if you click the "scroll right" button (which probably redraws them).
EDIT:
I'm also having some trouble with units on slopes, I think the drawing order is a bit off:
