An '''opposing force''' (alternatively '''enemy force''', abbreviated '''OPFOR''' or '''OpFor''') is a [[military unit]] tasked with representing an enemy, usually for training purposes in [[War exercise|war game]] scenarios. The related concept of [[aggressor squadron]] is used by some air forces.

At a basic level, a unit might serve as an opposing force for a single scenario, differing from its 'opponents' only in the objectives it is given. However, major armies commonly maintain specialized groups trained to accurately replicate real-life enemies, to provide a more realistic experience for their training opponents. (To avoid the diplomatic ramifications of naming a real nation as a likely enemy, training scenarios often use fictionalized versions with different names but similar military characteristics to the expected real-world foes.)

There are three major training centers that utilize home-based OPFOR units for the [[US Army]]:

* The [[National Training Center]] (NTC) at [[Fort Irwin, California]]—home unit is the [[11th Armored Cavalry Regiment]] (the ''Blackhorse'')<ref>{{cite web|url=http://www.forthoodsentinel.com/news/brave-rifles-opfor-dominates-at-ntc/article_c5347e44-7a1b-11e8-8d7b-d3f18cc18bec.html |title=Brave Rifles OPFOR dominates at NTC|date=28 June 2018 }}</ref>

Various US military installations or major units have their own local versions of opposing force used for training exercises. The joint Australian–US military exercise "Crocodile '03" featured an Australian-led opposing force in which soldiers from a range of Australian units worked together with a [[US Marine Corps]] contingent.<ref>{{cite news |title=Exercise Crocodile '03: You win some, you lose some |first=John |last=Wellfare |url=http://www.defence.gov.au/news/armynews/editions/1084/features/feature01a.htm |publisher=Army: The Soldiers' Newspaper}}</ref>

Several [[state defense force]]s have served as OPFOR units when training with the [[National Guard of the United States|National Guard]].
