(1) Do you use reverse movement hotkey for vehicles at all? On the one hand it is useful for avoiding the vehicle in question starting to turn around instead of moving straight backwards, although on the other hand you lose additional time on locating and pressing the U key. Maybe some of you use the grid-based hotkey system where all keys are concentrated near the left corner of the keyboard and so minimize the loss of time mentioned above?

(2) When playing as the USF I encounter something that looks like a bug but it doesn't seem this happens to others (at least as much as I've inquired): the ambulance truck stops reinforcing/healing units near it. The truck is stationary, and I have resources for reinforcing/healing, but it just doesn't happen. Am I missing something or is this a bug?

(3) From your experience, is it more efficient to use the Rifles as line infantry and Thompson Paratroopers for flanking or Browning Paratroopers as line infantry and BAR Rifles for flanking?

(4) How do you circumvent the lack of smoke abilities for OKW when facing Maxim/50 cal defensive lines?

(5) Is there a way to set up sandbags or other kind of green cover as the Ostheer, other than using doctrinal abilities like trenches? I'm pretty sure there isn't, but still wanted to double-check.
