The '''United Nations Space Command Defense Force''' ('''UNSC Defense Force''' or '''UNSCDF''' for short) is the defensive military force of the [[United Nations Space Command]], consisting of the [[UNSC Air Force|Air Force]], [[UNSC Army|Army]], [[UNSC Marine Corps|Marine Corps]], and [[UNSC Navy|Navy]], which serve as a joint air, land, and space force. <ref>[http://halostory.bungie.org/oconnor_mclees_080508.html HBO Interview with Frank O'Connor and Robert McLees]</ref>

==Background==
===Interplanetary War===
{{See also|History of the UNSC}}
The UNSC Defense Force was likely created during the [[Interplanetary War]], once the structure of the [[UNSC]] was formed. As a result of the UNSC's complex command structure, the UNSCDF is assigned to serve a ground and aerial defense force. Before it was destroyed by the Covenant in 2552, [[Reach]] served as the dominant UNSCDF military base, with numerous shipyards and docking stations, barracks and training facilities, and twenty [[Orbital Defense Platforms]]. It is likely that the UNSCDF has elements stationed on other planets within the [[Solar System]], besides [[Earth]]. [[Mars]] was one such colony that housed UNSCDF elements. <ref>''[[Halo: Uprising]]'', Ackerson's interrogation</ref>

===Human-Covenant War===
During the [[Human-Covenant War]], the UNSCDF was called into action on [[Earth]], and possibly [[Harvest]] as well.<ref>''[[Halo: Contact Harvest]]''</ref> The most notable military engagement the UNSCDF has participated in is the [[Battle of Earth]].<ref>''[[Halo 2]]'', "[[Cairo Station (Level)|Cairo Station]]"</ref> The UNSCDF, as a planetary defense force combining all branches of the UNSC, has multiple command bases situated in various regions of Earth such as [[Crow's Nest (Base)|Crow's Nest]] in [[Republic of Kenya|Kenya]].<ref>''[[Halo 3]]'', "[[Crow's Nest (Level)|Crow's Nest]]"</ref>

==Organization==
As the main military branch of the [[UNSC]], the UNSCDF is comprised of three autonomous or semi-autonomous branches, each with different functions and methods, but all unified under one command, and tasked with the protection of humanity, and the protection and recapture of human-occupied colonies. Control is exercised through regional [[Central Command|CENTCOMs]], which have authority over certain areas of space.

So far, the best-known members of the UNSCDF seem to be the [[Navy]] and [[Marine Corps]], likely due to the space-oriented nature of [[Human-Covenant War|26th Century warfare]]. While also a part of the UNSCDF, the [[UNSC Army|Army]] and [[UNSC Air Force|Air Force]] are less well known.

==Rank Structure==
The rank structure of the UNSCDF is similar in many ways, though most enlisted ranks are highly differentiated.

==Bases, Outposts, and Command Centers==
[[Image:UNSCDF.jpg|200px|thumb|A UNSCDF assembly aboard the ''Cairo'' [[Orbital Defense Platform|ODP]].]]
Unlike the [[UNSC]], the UNSCDF probably has a larger network of operations bases and command centers on [[Earth]]. Aside from ground centers, the UNSCDF also operates the [[Orbital Defense Platforms]] about [[Earth]]<ref>''[[Halo 2]]'', ''[[Cairo Station (Level)]]''</ref> and possibly even the [[Solar System]]. 

===Earth===
====Ground Bases====
*'''[[Crow's Nest (Base)|Crow's Nest]]''', [[Africa]], [[Republic of Kenya]]
*'''[[Outpost C9]]''', Africa, Republic of Kenya
*'''[[HIGHCOM Facility Bravo-6]]''', [[Australia]]
*'''[[Base Segundo Terra]]''', [[North America]], [[Mexico]], [[Mexico City]]
*'''[[Diego Garcia]]''', Indian Ocean
*'''[[Chawla Base]]''', North America, [[United Republic of North America]], [[Boston]]

====Orbital Defense Platforms====
*'''[[Cairo Station]]'''
*'''[[Malta Station]]'''
*'''[[Athens Station]]'''
*'''[[Nassau Station]]'''

==UNSCDF Weaponry==
The weapons used by the UNSCDF are manufactured to the highest standards in the UNSC. Despite this, they can rarely compete with Covenant weapons. They are listed [[:Category:Human Weapons|here]].

==Major UNSCDF Events==
*[[Interplanetary War]] - [[2160-2200]]
**[[Jovian Moons Campaign]]
**[[Rain Forest Wars]]
**[[Argyre Planitia Campaign|Martian Campaign]]
*[[Inner Colony Wars]] - Unknown, probably 25th century
*[[Human-Covenant War]] - [[2525]]-[[2553]]
**[[Fall of Reach]]
**[[Battle of Earth]]
**[[Battle of Mare Erythraeum]]
