I know it’s a bit late in the game for suggestions, but I have an idea for how cover is designated when you’re moving soldiers. Right now, the designation is more about the height of the cover. I might be more helpful if it indicated instead how much of your body is covered, i.e., more than half or less than half.
Yeah I think it will confuse quite a few new players, as they are conditioned to treating high cover as unconditionally better then half cover. Maybe something more in terms of posture icon would be a better fit (standing icon for full cover, crouching icon for half cover).
Still could be misleading, as it all depends from where enemy will shoot at your soldier.
It would be better to change icon to indicate stance of soldier as Wormerine said.
It is explained in the tactical tutorial now.
