Opposing force

(Redirected from OpFor)
This article is about a military term. For the game, see Half-Life: Opposing Force.
The term "opposing force" is occasionally used to refer to a genuine military foe. This article is concerned only with its use in simulated conflict.

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 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.)

In the French Army, a FORAD (FORce ADverse, enemy force) is used to train the army, in both the centre d'entraînement au combat (CENTAC, Combat Training Center) of Mailly-le-Camp[2] and in the centre d'entraînement aux actions en zone urbaine (CENZUB, Urban Operations Training Centre).[3] Declassed AMX-30 tanks were used to simulate Soviet T-72s,[2] until 2018.[4]

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

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.[8]

Several state defense forces have served as OPFOR units when training with the National Guard. The California State Guard,[9] the Georgia State Defense Force,[10] and the New York Guard[11] have provided OPFOR services to their respective National Guard counterparts. In 2018, the Georgia State Defense Force established the OPFOR Battalion[12] to assist National Guard Soldiers with pre-deployment training.
