10 Best Military Simulation Games of 2026

Arma 3 takes the top spot because no other game here combines this much military simulation with such a low price. Bohemia Interactive's Steam page lists over 40 vehicles you can drive and pilot, over 80 weapons with configurable attachments, and more than 610 km² of terrain across five maps, and the Apex and Contact expansions are now part of the base game. Ballistics are realistic and teamwork matters, but what keeps Arma 3 at the center of the milsim scene is its tooling: the Eden editor, Zeus mode for live Game Masters and a Steam Workshop with over 160,000 user-made items. That is why long-running community units still run their operations on it. Steam reviews are Very Positive at 91% of 111,719 English reviews. The trade-offs: the engine dates from 2013, much extra content is paid DLC, and the deepest experience needs a group, mods and patience to learn the controls.

Squad ranks second because it delivers the most structured large-scale tactical play here without Arma's learning curve. Offworld's Steam page describes 50 vs 50 battles in which each player joins a nine-person squad, across 13 factions and 24 maps. Picture-in-Picture scopes and a suppression system shape firefights, and a building and logistics system lets teams place HMGs and AT guns, fortify with sandbags and razor wire, and keep ammunition flowing. The in-game VoIP covers local, squad, squad leader and commander channels, which is the real heart of the game. Update 10.1 added Fireteam, a co-op PvE mode for up to five players with four missions open to every owner. Steam reviews are Very Positive at 83% of 84,223 English reviews, though the last 30 days dip to 78%. It is multiplayer focused, so solo players get little, and it asks for 65 GB of storage and a 6 GB graphics card.

DCS World is the deepest military simulator on the list and the best free entry point into realistic air combat. Eagle Dynamics' Steam page says its goal is the most authentic simulation possible of military aircraft, ground and armor vehicles and naval units. The free download includes the Su-25T attack jet, the TF-51D Mustang, the Caucasus map with 20 operational airbases and the Mariana Islands, plus a Mission Editor and network play with hundreds of AI weapons systems. From there, paid modules add aircraft such as the F/A-18C Hornet, F-16C Viper and AH-64D, and maps such as the Persian Gulf, Syria and Normandy 1944. VR works through SteamVR and Oculus. Steam reviews are Very Positive at 84% of 23,374 English reviews. It sits third rather than first because the hardware bar is high, at 16 GB of RAM, an 8 GB graphics card and 200 GB of storage, and the full systems take weeks to learn.

Arma Reforger is the newer Arma, and it suits players who want the series' realism with easier modding and friends on other platforms. The Steam page describes a Cold War sandbox with detailed ballistics, map and compass land travel, and weapons and vehicles from the M16 to the BTR-70. Conflict matches can run from an hour to days, Game Master lets one player build and run missions live, and Combat Ops and Capture & Hold cover co-op and faster play. Solo players get the five-mission Operation Omega campaign and a 1989 campaign on Kolguyev, one of three islands. Mods come straight from the in-game Workshop, and Steam lists cross-platform multiplayer and full controller support. Reviews are Mostly Positive overall at 79% of 32,791 English reviews and Very Positive recently at 83%. It ranks below Arma 3 because it costs $10 more, has a narrower official setting and requires DirectX 12.

GHPC (Gunner, HEAT, PC!) is the tank simulator to pick if you want realistic armor without a military training budget. Radian Simulations' Steam page sets it in a fictional 1985 war between NATO and the Warsaw Pact in central Germany, with units from the USA, USSR and both German states. The Early Access build has over 50 playable combat units, from tanks and IFVs to APCs and anti-tank missile emplacements, and every one has its gunnery optics and fire control modeled. You can fight from a single vehicle or lead a platoon of AI teammates through semi-randomized skirmishes and a basic campaign. Reviews are Very Positive at 91% of 5,085 English reviews, the highest share on this list alongside Arma 3. The limits are clear on the page: it is single-player until the roadmap adds multiplayer, there is no release timeline, and the developer warns that hardware demands are currently high.

Hell Let Loose is the best World War II pick here, built around the same 100-player teamwork that makes Squad work. Expression Games' Steam page describes 50 vs 50 battles on to-scale maps recreated from aerial and satellite imagery, from Omaha Beach and Carentan to Stalingrad and Kursk, with North Africa as well. Players choose from 14 roles across Command, Infantry, Recon and Armour units, crew tanks such as the Tiger and Sherman, and use anti-tank guns and artillery. The Commander spends resources to call in bombing runs, strafing runs and vehicles, which adds a strategy layer above the squads. Each map has 99 capture point variations, and voice chat runs on proximity, unit and command channels. Steam reviews are Very Positive at 83% of 63,039 English reviews. It ranks fifth because it is multiplayer only, costs $49.99, and recent reviews have slipped to 75%.

GROUND BRANCH is the slow, small-unit counterweight to the big battles above it. BlackFoot Studios casts players as the CIA's Special Activities Center paramilitary teams and aims to revive the tactical realism of late 1990s shooters. Its True First-Person system puts the camera at the character's eyes and fires bullets from the muzzle, so an exposed foot can be shot and rifle length matters in close quarters. Loadouts go down to individual pouch and attachment placement, with encumbrance and stamina penalties, and there are no unlocks or loot boxes. Play is 8-player co-op or 8v8, with a range and killhouse for practice and built-in positional voice plus team radio. Steam reviews are Very Positive at 83% of 15,331 English reviews, but recent reviews are Mixed at 60% of 89 after the July 16, 2026 release. Single-player with AI teammates is still marked as planned, and the minimum spec is 16 GB of RAM.

Operation: Harsh Doorstop is the free way into team-based milsim. Drakeling Labs, whose team includes developers of the cancelled Project Reality 2 project, describes it as a tactical shooter sandbox that mixes classic military simulation with mod-friendly design. Matches combine infantry and vehicles, teams build fortifications and supply lines with sandbags and barriers, and voice chat runs on local, squad and command channels, the same structure Squad players know. It also offers single-player and co-op modes, which Squad and Hell Let Loose lack. The Steam Workshop does much of the heavy lifting, with community factions, vehicles, weapons, modes and total conversions. Overall English reviews are Mostly Positive at 71% of 11,219, but the last 30 days are Very Positive at 88% of 168. It ranks eighth because it is still in Early Access and its official content is thinner than the paid games above it.

Command: Modern Operations is the pick for players whose idea of realism is running a whole war rather than one rifle. Its Steam page calls it a simulator of modern cross-domain warfare that puts you in the chair of a tactical and theater commander, directing air, surface, subsurface, ground, space and cyber operations. It is the commercial sibling of Command Professional Edition, and its engine models real-world ballistics, sensor degradation, ocean thermal layers and line-of-sight geometry. Rather than micromanaging, you set Weapon Release Authorities, EMCON policies and patrol behaviors and let the AI fly and sail. Scenarios span post-WWII clashes to near-future conflicts, with real-time multiplayer and a level editor. Reviews are Very Positive at 85% of 1,455. It ranks ninth because $79.99 is the highest price here, the interface is a map with unit symbols, and the doctrine system takes real study.

Combat Mission Shock Force 2 is the tactical wargame on the list, for players who would rather command a company than carry a rifle. Battlefront's Steam page sets it in a hypothetical conflict in Syria, with US Stryker and Heavy Brigade Combat Teams facing Syrian Army infantry, mechanized and armored units, plus irregular forces and IEDs. Every soldier and vehicle is portrayed at 1:1 scale, and vehicle damage tracks each subsystem along with ballistics and armor effects. Battles run in real time or in WeGo, where both sides plan 60 seconds and then watch the results together, with replays, play by email and hotseat. There is the Task Force Thunder campaign, over a dozen standalone battles, unlimited Quick Battles and a full editor. Reviews are Very Positive at 80% of 627. It ranks last because the $59.99 base price grows with $34.99 modules and the interface is demanding for newcomers.
