Soldiers in Phoenix Point are too expensive to be disposable, but you have limited control over who to recruit or what you can do with them, so generally just take whoever shows up without much attachment. New recruits? Oh, but he's a heavy, so I can only give him terrible weapons that don't fit into my strategy. Or there's this sniper but her only good skill is biochemist, which is wasted on single shot weapons, plus she can't use any of my guns.
