Manji Formation (Earth-2356)

The Manji Formation is a very basic formation that is used to protect a central point, to defend against multiple attacks coming from multiple locations, or to defend a group against an attack that could come from any unknown angle. Each person is responsible to guard against the area straight ahead of them and to the left. This formation has one blind spot: the centre.
