9 Best Free Military Games of 2026

War Thunder ranks first because no other free military game covers as much ground. Gaijin's Steam page lists more than 3,000 aircraft, helicopters, tanks, warships and other vehicles, 100 maps based on historical theaters, PvP at several difficulty settings and PvE campaigns. Players on Windows, Mac, Linux, PlayStation 4 and 5, Xbox One and Xbox Series X|S share the same servers, which no other game here matches. You can play every vehicle class without paying. The US Steam store sells starter packs from $4.99 for the US and German trees, $7.99 for the USSR and $9.99 for the others, while top premium jets cost $79.99. Over its lifetime, 72% of 331,237 Steam reviews are positive, but the last 30 days dipped to 68%. The PC install needs 70 GB, 4 GB of RAM and a GTX 660 class card at minimum, so it runs on modest hardware. If you want one free game for tanks, planes and ships, start here.

Call of Duty: Warzone is the free way into the series that most people mean when they say military shooter. The Steam listing for the Call of Duty app describes Warzone as a massive free-to-play combat arena with Battle Royale and Resurgence, and the official site offers it on Xbox, PC through Battle.net and Steam, and PlayStation. Call of Duty Points start at $1.99 for 200 CP in the US store and carry over to Modern Warfare 4 and Black Ops 7, which cost $69.99 each if you later want the full games. There are two practical hurdles. Activision notes that a mobile phone number linked to your Activision account may be required, and the PC install needs 115 GB on an SSD. Steam reviews of the shared Call of Duty app are mixed at 57% of 242,588 positive, but those reviews cover the paid games too. For fast modern infantry combat, it is the clear free pick.

Enlisted solves the empty-battlefield problem of many free shooters by giving every player a squad. According to the Steam page, you command a squad of AI soldiers and can switch to another when one dies, so battles feel large even on quiet servers. It recreates fronts from Normandy and Berlin to Stalingrad, Tunisia and the Pacific, with four nations, around 400 vehicles and 18 soldier classes that include flamethrowers, anti-tank guns and paratroopers. A built-in mission editor lets players publish missions to public servers. The US Steam store sells starter packs for $4.99 per nation and squad packs from $19.99 to $34.99, none required. Steam reviewers rate it 78% positive from 21,114 reviews. The limits are the setting, which is World War II only, kernel-level BattlEye anti-cheat, and 8 GB of RAM at minimum. For free World War II combat with infantry, tanks and planes, it is the strongest option.

World of Tanks is the pick for players who want to think before they shoot. Wargaming's Steam page describes 800+ vehicles over 11 tiers and 11 nations, split into light, medium and heavy tanks, tank destroyers and self-propelled guns, each with its own role. The core is 15v15 Random Battles, with Onslaught 7v7, Frontline 30v30 on large maps and the Steel Hunter battle royale on top, plus clan play through Global Map and Strongholds. New players get Bootcamp scenarios. It costs nothing to play; the cheapest item in the US Steam store is an $8.99 customization pack, a Premium Month Pack is $19.30 and premium tanks run up to about $57. The trade-offs are size and scope: the install needs 120 GB and the Steam version is Windows only. Steam reviewers rate it 73% positive from 25,687 reviews. Pick it if you want tanks only and a tactical pace.

Delta Force covers two kinds of military shooter in one free game. Its Steam page describes an operator-based extraction mode, where squads loot maps, fight armed bosses and rival teams, then extract by rocket, wingsuit or sewer pipe, and a Warfare mode where 64 players fight with tanks and helicopters across urban, mountain and island maps. Weapons are real-world models you can customize and share, and vehicles can be modified too. Between raids, loot upgrades an Operations Center that expands stash space and unlocks gear. The game is free to play with in-game purchases and lists cross-platform multiplayer. The caveats: it needs a LEVEL INFINITE account, 8 GB of RAM and 88 GB of disk, and player opinion has cooled, with 65% of 70,194 Steam reviews positive overall and 53% in the last 30 days. If you want large vehicle battles with a modern setting, it is the closest free option.

World of Warships is the free military game for players who would rather command a ship than run with a rifle. Wargaming's Steam page lists more than 800 ships from the first half of the 20th century, including battleships, destroyers, cruisers, submarines and aircraft carriers, spread across 13 national tech trees. You can team up with friends in a Division or join a clan and compete in the clan league, and you shape each ship with modifications, commander skills and camouflage. The game costs nothing; the US Steam store sells packs from $3.00 up to about $24. It holds one of the better review ratios here, 79% positive from 49,736 Steam reviews, and its minimum spec of 6 GB of RAM and a GT 640 class card suits older PCs, though it needs 67.2 GB of storage. The limit is scope: it is naval combat only. For ships, it is the clear free choice.

Arena Breakout: Infinite is a free take on the hardcore extraction shooter, built for players who like military gear. Its Steam page describes 6 maps that range from indoor close quarters to open wilderness, dynamic weather including night, fog and blizzards, and over 75 weapons with 900+ mods across more than 20 attachment slots. Raids come in three difficulty tiers, Normal, Lockdown and Forbidden Zone, and modes include Tactical Ops, Solo Ops and Covert Ops. On cheating, it offers killcam replays with one-tap reports and automatic in-game compensation when a loss to a cheater is confirmed. It is free to play on PC and rated 77% positive from 37,907 Steam reviews. It is harder to learn than the others here, since a failed raid costs your loadout, and the minimum spec asks for 12 GB of RAM and 70 GB of storage. Choose it for tense, slow, realistic raids.

PlanetSide 2 is the free game for players who care most about scale. Its Steam page calls it a massively multiplayer FPS in which battles involve hundreds of soldiers, not dozens, across four continents with dozens of square kilometers of contestable ground. Players join one of three empires, the Terran Republic, New Conglomerate or Vanu Sovereignty, each with its own weapons and vehicles, and fight on foot, in ground vehicles and in aircraft. The war persists, so holding territory and resources matters beyond a single match, and a class system with a skill tree lets you fit a role in your squad or outfit. It is free to play and rated 81% positive from 47,575 Steam reviews, the best ratio here. The downsides are age and setting: it launched in 2012, uses a sci-fi world rather than real armies, and recent reviews have slipped to 62%. Its 20 GB install is the smallest on this list.

Battlefield REDSEC is EA's free entry point to Battlefield, released on October 28, 2025. The Steam page describes Battle Royale at Fort Lyndon, a redacted military facility in Southern California, with large-scale destruction and squad play, plus Rapid Royale, a faster variant with lower player counts, redeploys and quick circles. Tactical Destruction lets you blast through walls and enemy positions, and every player gets free access to Portal for building custom experiences. EA's site offers it through the EA app, Steam, Epic Games Store, PlayStation and Xbox. Battlefield Coins start at $4.99 for 500 BFC and work in Battlefield 6 too. It ranks last because player reception is weak: only 42% of 9,780 Steam reviews are positive, and EA requires a persistent internet connection and an EA account. If you like Battlefield destruction and want battle royale, try it; for full-scale warfare, Delta Force or War Thunder fit better.
