The Usonian Unarmed Bunker is a structure that can usually be constructed by Usonian Engineers. It is a fortified building without weapons that can be rotated to face any direction , so it is necessary to choose locations visible to soldiers when building it. That's important, because it can be upgraded to an Usonian Flame Bunker. Players can man the bunker with an infantry squad. The Infantry-Squad is able to shoot in all directions.
Compared to bunkers of other factions, it has descent health, but the garrisoned infantry can fire in all visible directions
