Give the SL armour a squaddie tracker. The tracker would operate the same as the IO detector/motion detector, except it only works for 1) marines in the same squad as the SL 2) only revivable but already downed/in critical marines. Make the thing only usable by the SL as well, toggleable like the suit light.
This would make locating walled in marines easier and it would give an incentive to the squad to actually keep their SL alive (right now, there is not much unless you know/like him to begin with).
