They are hidden unless they attack, which un-hides them for the remainder of the turn. You can also see them if they are engaged in melee.
So letting them wait to act at the very end of the turn would grant them impunity? Unless enemy made their ranged wait as well (but then with their high initiative they would still act before you). Or will they be still exposed at the beginning of the next turn?
Anyways, you are talking about late-game and sekata is talking about early game if I understand that correctly.
No, I am talking about early to mid game. Raiders are meant to be challenging early on. You aren’t supposed to plow through hordes or raiders and marksmen without effort. At last that’s what I think. later there are other challenges.
