Boundary

A boundary is a region of a Battlefield map where players are not allowed. Boundaries serve to contain players within areas of a map chosen by map designers so they cannot wander away or exploit features not properly modeled.

There are typically two kinds of boundaries: a smaller one beyond which ground forces cannot cross, and a larger one beyond which aircraft are forbidden. The size of the boundary can change depending on how many players the map was designed for, as can the location of spawn points, control points, and commander resources.

Straying beyond either boundary results in a 15-second countdown and an on-screen warning. If the player does not return to the battlefield in time, they are automatically killed. Some games use artillery as a justification; others simply cause the player to disappear.

On certain maps, it may be possible to maneuver around a building placed at a boundary, bringing up opportunities to flank the enemy.

On those games with Commander view, the commander may not place orders or assets beyond the map boundary.
