A '''combat barrier''' is a mobile ground barrier used by [[United Nations Space Command|UNSC]] infantry forces. They can be deployed and set up relatively quickly to aid the defense of a strategic position.<ref>''[[Halo: Combat Evolved]]'', campaign level, ''[[The Pillar of Autumn (Halo: Combat Evolved level)|Pillar of Autumn]]''</ref><ref>'''[[Halo 2]]''', campaign level, ''[[Cairo Station]]''</ref><ref>'''[[Halo 3]]''', campaign level, ''[[Crow's Nest]]''</ref>

==Role==
Combat barriers are placed and situated all around strategic locations as defensive mechanisms against enemy [[weapons]] flanking fire. Several types of barriers exist, but all are made of thick battle plating, presumably made of titanium or titanium-ceramic [[armor]]. These barriers cannot be moved or be deployed.

Combat barriers are used to protect soldiers of all types that are located in bases, dug-in fortifications, and other facilities (such as ships). While they are almost impenetrable to [[plasma]] and projectile weapons, they do not protect well against the concussive force of an explosion, though they do a good job of absorbing shrapnel and flying debris.

The UNSC's two principal models of combat barrier — the [[:File:Mobile shield 1.jpg|M72-S]] (small) and [[:File:Mobile shield 2.jpg|M72-L]] (large) mobile armors — work by manipulating lines of sight. They have a small slit, opening or corner for someone inside to shoot out of and have full line of fire on his enemies, but the enemies must hit a very small target. Some combat barriers however, lack these slits - combatants using them for protection must stand up or creep out from the side to fire on an enemy, exposing themselves in the process.<ref>'''[[Halo 3]]'''</ref> Beside the more common barriers made of metal, the UNSC also uses large concrete barriers.
