Mines still wipe full health soliders, but not more than 2 of a squad, right? But for mortars, I would prefer a nerf by decreasing the shell damage, so that a single shell cant kill a full health soldier or squad anymore in case it hits the target directly

Those mortar one-hits only would make sense if the Player would be forced to invest more micro in those units by manual fire... but auto-fire-mode LONG RANGE units definetely deserve no one-shots as reward
