Is better to place two high reaction trooper at each flank of the door and send a rookie nearly unarmed but with an activated high explosive.

I dont like to complety clear an area as preventive meassure but for save an exposed veteran is good enough to make holes trough the buildings. Anyway i dont like the artillery play, but at night battles or when beeing outgunned and outclassed it can be the solution.
