10 Best Military Games for PC of 2026

Arma 3 ranks first because it covers more of modern warfare than any other PC game here and costs $29.99 on the US Steam store. Bohemia Interactive's store page says you can drive tanks, fly jets, command a squad or play a range of infantry roles, with realistic ballistics across large open maps such as Altis, Stratis and the Tanoa jungle. The Apex and Contact expansions now come with the base game, which adds the Apex Protocol co-op campaign and the First Contact story to the East Wind campaign. Online, the official Combat Patrol, Escape and Warlords scenarios sit beside Zeus, where a Game Master curates a live battle for other players, and Steam Workshop support keeps community content flowing. The minimum spec is a quad-core CPU, 8 GB of RAM and 50 GB of storage. The drawbacks are real: the game dates from 2013, controls take time to learn, and most milsim groups expect you to install their mod list.

Battlefield 6 is the best pick for PC players who want big military battles without a milsim learning curve. EA's Steam page promises infantry combat, aerial dogfights, tank warfare and naval fights in one game, with destructible environments you can use for a tactical edge. A single-player campaign follows an elite squad of Marine Raiders, and multiplayer runs on maps set in Cairo, Brooklyn, Gibraltar and Japan. Battlefield Portal turns the game into a sandbox where creators can move, scale and duplicate objects, script NPCs and build their own modes. The Kinesthetic Combat System adds movement such as crouch sprinting and dragging a downed teammate while reviving. It supports cross-platform play and full controller input. The catch is cost and hardware: $69.99 at full price, 16 GB of RAM and an RTX 2060 as the minimum, and a TPM 2.0 plus UEFI Secure Boot requirement that rules out some older machines.

Squad is the best modern military shooter on PC for players who want realism without Arma's full simulation overhead. Offworld describes it as a tactical FPS that sits between arcade shooters and military realism, with 100-player battles, combined arms warfare and base building. Each side fields 50 players split into nine-person squads, and the game ships with 13 factions, 24 large maps and faction-specific weapons and vehicles. Picture-in-Picture scopes magnify only the optic, which makes long-range fights feel closer to real sights. Update 10.1 added Fireteam, a PvE co-op mode for up to five players, with four missions free for every owner and optional Supporter and Founder packs. At $39.99, Squad costs $10 more than Arma 3 and asks for 65 GB of storage. It has no campaign, and the store page itself lists a teamwork oriented mindset under requirements, so players who want to play alone should look elsewhere.

Hearts of Iron IV is the best military strategy game on this list for players who want to fight a war from the top. Paradox Development Studio calls it a grand strategy wargame: you take charge of any nation in World War II, build its industry, form alliances and decide whether to restore democracies or monarchies along alternate history paths. The depth sits in the details, from designing division templates for your armies to setting factory production and research. The current Steam purchase includes four expansions, Death or Dishonor, Together for Victory, Waking the Tiger and Man the Guns, and the game has Steam Workshop mods and multiplayer. It is also the easiest game here to run: 4 GB of RAM and 2 GB of storage, on Windows, macOS or Linux. The cost is time. The interface is dense, mouse and keyboard are required, and several newer expansions are sold separately on top of the $49.99 price.

Insurgency: Sandstorm is the best value military shooter on PC for players who want realism in smaller, faster fights. New World Interactive describes it as a hardcore tactical FPS built on lethal close-quarters combat, and the Steam page lists no crosshair, a minimal HUD and realistic damage. You manage ammunition, pick specialized classes and use a spotter to call artillery and support strikes, with light attack vehicles in some modes. PvP matches run up to 14 vs. 14, and co-op missions put your squad against AI, which makes it easier to learn than Squad or Hell Let Loose. It supports cross-platform play and full controller input. The minimum spec is modest: 8 GB of RAM, a GTX 760 and 40 GB of storage. At $29.99 it matches Arma 3 as the cheapest full-price game here. The limits are scale and age: matches are a fraction of the size of the 100-player games, there is no story campaign, and it launched in 2018.

Hell Let Loose is the strongest World War II pick for PC players who want large battles with a chain of command. Expression Games builds each match as a 50 vs. 50 fight on to-scale maps recreated from aerial and satellite imagery of real locations, including Carentan, Omaha Beach, Stalingrad and Kursk, across the Eastern and Western Fronts and North Africa. You choose one of 14 roles in Command, Infantry, Recon and Armour units, from Officer and Spotter to Medic and Tank Commander. A resource-based, RTS-inspired meta-game sits on top of the shooting: officers and a commander direct the team, and supply chains and tanks decide where the front line moves. The minimum spec is 12 GB of RAM, a GTX 960 4GB and 60 GB of storage. It is a multiplayer-only game with partial controller support, and at $49.99 it costs more than Squad, which offers similar scale in a modern setting.

Arma Reforger is the modern way into Arma for PC players who want mods without the setup work of Arma 3. Bohemia Interactive sets it in the Cold War, with realistic weapons and ballistics, map and compass navigation, and Cold War gear from the M16 to the BTR-70 across several large islands. Modes cover most play styles: Conflict matches can run from an hour to days, Game Master lets you build and curate missions live, Combat Ops is co-op special operations and Capture & Hold is the fast option. Solo players get Operation Omega, a campaign of 5 replayable missions, plus Elimination and Air Support scenarios. Mods come from an in-game Workshop, so you do not need an external launcher. It supports cross-platform play and controllers, and needs 8 GB of RAM and only 20 GB of storage. The trade-off against Arma 3 is breadth: one era and a smaller arsenal for $10 more.

Call of Duty: Modern Warfare 4 replaces Black Ops 6 in this ranking because Black Ops 6 is now sold inside the wider Call of Duty app on Steam, while Modern Warfare 4 is the current standalone release at $69.99. Activision's store page sets the campaign during a North Korean invasion of South Korea: you play Private Park, a young South Korean soldier, while Captain Price runs an off-book mission, with levels in Korea, New York, Paris and Mumbai. Multiplayer brings back large maps that mix vehicles and infantry alongside close-quarters maps, and DMZ is an extraction mode you can play solo or with a squad. It supports cross-platform play and controllers, and the minimum spec is a modest 8 GB of RAM with a GTX 970 or 1060. The downsides are the 115 GB install, the full $69.99 price and fast arcade pacing that will not satisfy players looking for Squad or Arma style realism.

Company of Heroes 3 is the pick for PC players who want military strategy at squad level rather than nation level. Relic Entertainment sets it in the Mediterranean, from the deserts of North Africa to Italy, with two campaigns and four factions for multiplayer and co-op. A Dynamic Campaign Map lets you command ground, air and naval forces and build supply lines between real-time battles. Full Tactical Pause lets you stop a battle and queue orders, which lowers the barrier for newer RTS players. In combat, flanking exposes side armor, infantry can breach garrisons, and elevation affects line of sight on destructible maps. The minimum spec is light: 8 GB of RAM and a GTX 950. It lists at $59.99, though Steam showed it at $19.79 on sale when we checked. The faction roster is smaller than Hearts of Iron IV's choice of any nation.

GROUND BRANCH is for PC players who miss the slow, planned tactical shooters of the late 1990s. BlackFoot Studios, which includes one of the developers behind the original Rainbow Six and Ghost Recon, casts you as the CIA's Special Activities Center/Special Operations Group leading deniable operations worldwide. Its True First-Person System puts the camera at your character's eyes and fires bullets from the muzzle, so a foot sticking out of cover can be seen and shot. Loadouts go down to individual pouch and attachment placement, and an encumbrance and stamina system punishes overpacking. Steam lists single-player, co-op and PvP play with Steam Workshop support, and the store page dates its release to July 16, 2026. At $29.99 it ties Arma 3 and Insurgency: Sandstorm on price, but asks for 16 GB of RAM. There are no vehicles or large battles, so it suits small squads rather than players who want combined arms.
