Maybe I am missing something here, how often do people use this new feature? In my case not often.
Most use would be units I turn the range down on, so typically scouts if I think the area is dodgy, also on the rare occasion in battle.

It is useful for ranged fire if there are no closer units, Tank or MG say firing at 1000m you might well drop out of sight.

In most cases in an infantry fire fight its not that useful, there are odd times its beneficial but that's it. In most cases I want to use that 2mp to fire as I have target lock.
Watch what happens when the AI goes to ground or seeks cover, at close range it normally vanishes then reappears because someone sees it.
So that's 2mp to POSSIBLY break target lock why not just fire another unit & do so for sure or if the units in big trouble pop smoke.
Multiple units have target lock on a unit sure you can try but that means lots of eyeballs on you. In that case I do the standard thing of stop shooting with them & let them use op fire next go to take the heat off them.

Am I missing something because I have no trouble keeping track of the few times I take attempt to take cover.

Taking up positions for say an ambush I suppose you could C key every unit but if they are stationary for a turn I assume the game does this automatically. As I don't know if it worked why try again?
