The point-defense gun fills a role similar to the [[wikipedia:CIWS|CIWS]] designs created during the 20th century. Based around [[Magnetic Accelerator Cannon|magnetic linear accelerator]] technology,<ref name="ENC"/> it fires solid projectiles. Unlike [[Archer missile]]s and the [[Magnetic Accelerator Cannon|MAC]] weapon systems mounted on capital ships, the point-defense guns are not used to engage Covenant capital ships.  They are instead meant to intercept smaller threats like [[Type-31 Seraph]] fighters<ref>'''Halo: The Fall of Reach''', ''page 272''</ref> or [[Covenant boarding craft|boarding craft]], and disrupt incoming plasma weaponry,<ref>'''Halo: Warfleet''', ''page 19''</ref> to reduce the damage inflicted to a warship's superstructure.

Because [[human]] operators lack the reflexive responses necessary to operate the point-defense guns to maximum effect, the autocannons are computer controlled and, if an AI is available, control is diverted to it.

Point-defense guns have been standard armament on UNSC vessels since the [[Insurrection]], a common model being the [[M810 Helix point defense gun|M810 Helix]]. Later, {{Class|Halcyon|cruiser}}s used a dual-barreled point-defense weapon system designated as the [[M910 Rampart point defense network]].<ref>[http://halo.xbox.com/Content/assets/en-us/ONI/577839090903298928/DDR-A340024-1115-08-27-52.pdf Data Drop 5]</ref>
