What if using a medic box or getting a medic treatment would increase your chance to get knocked down instead of straight up killed (similar to the perk)? It’d turn the idea on its head a bit, but that might provide a bit more tangible benefit than healing dead troopers where the player might have already rotated out as well.
i would make colective grab of Medkits in medbag.
just press X, then all your soldier ‘‘reload’’ the medkits in the medbag.
that will heal all your squad in just one clik
