Collapse (Maneuver)

A Collapse maneuver occurs when a unit, defending a position that is significantly forward of other friendly units, is ordered to retreat closer to them.

This maneuver is executed when the forward defensive position becomes untenable to defend, posing a risk to the unit itself as well as a flanking opportunity for enemies. Collapsing the unit back into a closer position allows it to plug a gap in the defenses and allows other units to protect it more effectively.
