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. Combat barriers are used to protect soldiers of all types that are located in [[military base]]s, dug-in fortifications, and other facilities (such as ships). While many models of combat barrier offer decent protection from [[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 [[M72 Mobile Barrier]] is a principal type of combat barrier used by the UNSC, encompassing the M72-S (small) and M72-L (large) Mobile Barriers.<ref>[http://www.spartangames.co.uk/make-your-halo-table-look-awesome '''Spartan Games''': ''Make your Halo table look awesome!'']</ref> These barriers 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.
