[@CAS1006] Ah, then I must apologize because that kind of role will not be necessary.  If you're looking for a support role, though, how about this: One thing people have not thought of is someone who's looking after the team directly, someone who can shield them when they're at their weakest, prevent the X from swarming them, stopgap the enemy.  Active support instead of passive support.  If you could make a support character who is not on overwatch but in it with them, that would be a great boon to the mission.
