MW4 military units and factions

Modern Warfare 4’s campaign military units and playable Operator factions are separate references. The Republic of Korea Marine Corps belongs to the campaign context; the launch roster supplies the faction labels used for playable Operators.

Playable military units

Republic of Korea Marine Corps

The ROKMC (Korean: 대한민국 해병대; Hanja: 大韓民國 海兵隊) is the naval infantry of South Korea — a branch of the military responsible for amphibious operations, and also functioning as a rapid reaction force and strategic reserve. Active since April 15, 1949.

Its motto is 정의와 자유를 위하여 (“For Justice and Freedom”) and 필승 (“Certain Victory”).

In Modern Warfare 4, the ROKMC appears in the campaign as a playable faction. Its unit is Sierra-1.

The squad

Park Hyun-Jun is Private Park — the campaign’s player character, the young South Korean soldier facing live combat for the first time. The unit roster is the campaign’s squad, and MW4 puts the player inside a real Korean military unit rather than an ad-hoc team.

The naming convention is notable: Korean given names first, with the squad leader holding sergeant rank and the two most junior members being Privates and two Private First Classes.

French Army Special Forces Command

The Commandement des Forces Spéciales Terre (COM FST) is a grouping of the various special operations forces units of the French Army, and it is the command charged with overseeing them. Active since 2002.

COM FST makes its debut in Call of Duty: Modern Warfare 4. A COM FST operator is playable in Modern Warfare 4 Multiplayer, DMZ, and Call of Duty: Warzone 2.0.

This is the first time the French Army has a dedicated unit in the series, and it is the mechanical counterpart to the Vault Edition’s Special Forces Operator Pack — which includes a French operator skin with a French voice pack, alongside the UK, German and South Korean ones. The four nations in that pack now each have a military unit with a presence in MW4.

SAS

The Special Air Service is an elite special forces regiment of the British Army, appearing in Modern Warfare, Modern Warfare II, Modern Warfare III, Warzone Mobile and Modern Warfare 4.

SAS night raids are one of the campaign’s five named operation styles — the Mumbai operation. The unit’s history in the series is substantial:

• April 6, 2019 — Bravo Team (Price, Ghost, Soap and Corporal Burns, under Lieutenant General Herschel Shepherd) deployed to Verdansk. Ghost was tasked with defending Verdansk International Airport while the rest of the team went to the Acropolis National Arena, where they arrested Vladimir Makarov. The Inner Circle destroyed the airport with explosives planted beforehand.
• November 21, 2023 — SAS operators cornered off the abandoned street where Konni was possibly hiding, in the Modern Warfare III campaign.

United States Marine Corps

The USMC is the maritime land force branch of the United States Armed Forces, appearing in Modern Warfare, Modern Warfare II and Modern Warfare 4.

In MW4, the United States deploys a 10,000-man task force from the Marine Corps to defend Seoul, bound by treaty obligations established a century earlier. The USMC also has a long history in the series:

• Modern Warfare (2019) — the 1st Marine Raiders led by Sergeant Hoyt appear in “Fog of War” as the “Hitman” Team, and are wiped out by Al-Qatala insurgents led by Hadir Karim while extracting with the chemical gas, leaving Alex Keller a lone survivor. The Demon Dogs, led by Sergeant Griggs, appear in “Hunting Party”.
• Modern Warfare II — appears in the campaign.
• Modern Warfare 4 — the 10,000-man task force, the American response to the Korean invasion.

Metropolitan Police Service

The Met Police — the Met, or MPS — is the territorial police force responsible for Greater London, excluding the square mile of the City of London, which is the City of London Police’s responsibility.

In Modern Warfare they appear in the mission Piccadilly, assisting Kyle “Gaz” Garrick’s team against Al-Qatala terrorists. In Modern Warfare III they appear in Trojan Horse, and their vehicles can be seen in the multiplayer map “Underground”. Officers from the MPS are seen controlling the crowds during “Mind the Gap”.

Known members: Kyle “Gaz” Garrick, Raven, Crowley (K.I.A.), Monroe, Fowler (K.I.A.) and Brooks (K.I.A.).

Korean People’s Army

The KPA is the primary armed force of North Korea and the antagonist faction in MW4’s central conflict. In Advanced Warfare the KPA were the first antagonist faction the player encountered, and the United States was defending Seoul. MW4 inverts that — the KPA is on the offensive, and the player defends.

A pattern in the military units

What MW4 does with its unit roster is worth naming, because it is unusual for the series:

These unit identities provide campaign and character context. They do not establish a playable faction count or a comparison with every previous Call of Duty. The published Operator roster remains the source for selectable characters and their access requirements.

How does this relate to the launch roster?

Activision publishes 33 Operators for Multiplayer and DMZ in its launch roster. The complete playable list records the source’s faction labels and unlock criteria. Story characters, military units, skins and selectable Operators are different records; do not add them together as a roster count.
