commando smoke nade gives non directional yellow cover, and added
Speaking of which, wouldn't it be better to say that ability and Hit the Dirt makes the area/users count as being in light cover instead (which would therefore not stack with the defensive benefits of heavy cover)? Of course, it wouldn't be bad to state the actual defensive benefit of light cover in addition to that for the unaware.
Also, just wanted to make sure - the distinction between Wehr's Tactical Advance and USF's Tactical Movement is that the former lasts during retreat, yeah?
Thanks for the extensive work!
