Newb: Help me understand when I can use Battle Drills
I'm new to Blkout and enjoying the game. So far my biggest hang up has been with when I can use Battle Drills. Are these abilities I activate per unit, or do I use them at the beginning of the turn and everyone can use them that turn?
Also how often can I use them? Can I use them every turn for every unit or is there some kind of limit on them?
Thanks for the help!
