This is a list of all playable factions available in Squad. Most factions in-game are based on real-world armed forces; while a select few are either an amalgamation (such as Middle Eastern Alliance) or a generic representation of real-world para-military groups (such as Insurgents and Irregular Militia).
Playable factions determine the available Weapons and Vehicles to that team in a game of Squad. Some factions also determine the types of Maps they deploy on; e.g., Middle Eastern Alliance and Insurgents are most commonly seen on Middle Eastern and South Asian maps.
Consisting of NATO members and Western-aligned countries, conventional BLUFOR factions are high-tech militaries outfitted with modern equipment of western design.
Community-/fan-made factions in Squad (such as the Canadian Armed Forces) were free DLCs in the beginning, before OWI changed the system for community factions to be completely included into the basegame. Other content like the Weapon Camo Packs for example (which can affect gameplay, due to better camouflage of players in terrain), remain paid DLCs.
