=== Defense structures ===
Building structures which enable one's own [[soldiers]] to survive on the battlefield. Examples include trenches, bunkers, shelters, and armored vehicle fighting positions.{{citation needed|date=June 2018}}

Defensive [[fortification]]s are designed to prevent intrusion into the inner works by [[infantry]]. For minor defensive locations, these may only consist of simple walls and ditches. The design principle is to slow down the advance of attackers to where they can be destroyed by defenders from sheltered positions. Most large fortifications are not a single structure but rather a concentric series of fortifications of increasing strength.{{citation needed|date=June 2018}}
