The '''M870 Rampart point defense gun''' is a weapon system utilized by warships of human make, most commonly those of the [[UNSC Navy]]. They function as part of a ship-wide defensive network.<ref name= "WaypointFrigate">[https://www.halowaypoint.com/en-us/universe/vehicles/unsc-frigate '''Halo Waypoint:''' ''UNSC Frigate'']</ref> Each M870 Rampart turret is fully automated due to the inability of humans to calculate firing solutions fast enough for the role of the weapon,<ref name="Warfleet19">'''Halo: Warfleet''', ''page 19''</ref> and consists of of twin-<ref>'''[[Halo 3]]''', ''Charon-class frigate in-game model''</ref> or quad-mounted 50mm<ref name= "WaypointFrigate"/> rapid-fire coilguns and a targeting scanner.<ref name= "Warfleet 39">[[Halo: Warfleet – An Illustrated Guide to the Spacecraft of Halo|'''Halo: Warfleet - An Illustrated Guide to the Spacecraft of Halo''']], ''page 39''</ref> [[Point defense gun|Point defense guns]] such as these are used for the engagement of incoming threats, including the warding off of strikecraft and the disruption of [[Plasma torpedo]]es;{{Ref/Reuse|Warfleet19}} each emplacement actively switches between sub-caliber armor-piercing sabots or proximity detonation fragmentation shells based on a threat-analysis of its current target in order to maximise effectiveness.<ref name= "Warfleet 39"/> 

M870s are most commonly mounted on lighter [[frigate]] and [[corvette]] type [[UNSC]] and [[CMA]] vessels, including {{Class|Scholte|missile corvette}}s,{{Ref/Site|Id=CFFoundations|URL=https://www.halowaypoint.com/news/canon-fodder-foundations|Site=Halo Waypoint|Page=Canon Fodder - Foundations|D=12|M=01|Y=2022}}, [[Gladius-class heavy corvette|''Gladius''-class heavy corvettes]],{{Ref/Reuse|Warfleet19}} {{Class|Charon|light frigate}}s,<ref name="Bulletin 10.10.12">[http://blogs.halowaypoint.com/Headlines/post/2012/10/10/The-Halo-Bulletin-101012-.aspx '''Waypoint''': ''The Halo Bulletin: 10.10.12''] (defunct, backup on [https://web.archive.org/web/20130302031735/http://blogs.halowaypoint.com/Headlines/post/2012/10/10/The-Halo-Bulletin-101012-.aspx Archive.org])</ref> {{Class|Stalwart|light frigate}}s,<ref name= "Warfleet 37">'''Halo: Warfleet''', ''page 37''</ref> and {{Class|Strident|heavy frigate}}s.<ref name= "Warfleet 39"/> But they can also be found mounted on select heavier vessels, such as the [[Halberd-class destroyer|''Halberd''-class destroyers]],<ref name= "Warfleet 32">'''Halo: Warfleet''', ''page 32''</ref> and even the [[Epoch-class heavy carrier|''Epoch''-class heavy carriers]],<ref name= "Warfleet 40">'''Halo: Warfleet''', ''page 40''</ref> making them a relatively common fixture across the entirety of the UNSC fleet.
