Ground War in Modern Warfare 4 is 32v32 Combat Outpost, a Domination-style mode where teams capture Outposts for points and spawns and reinforce them for rewards up to a Light Tank. It has three maps around Hajin: Imjin Farmland, Wolves Stadium and Forest.
Ground War in Call of Duty: Modern Warfare 4 is Combat Outpost, a new 32v32 mode in which two teams capture Outposts for a steady stream of points and new places to spawn, then reinforce them to earn team rewards from a local UAV up to a Light Tank. It plays on three large maps in and around Hajin, the city of the campaign and of DMZ: Imjin Farmland, Wolves Stadium and Forest. A match runs 20 minutes or to 1,500 points, and parties of up to 4 can queue together.

How Combat Outpost works
Combat Outpost is "Domination reimagined" for Ground War, in Activision's words on the launch blog. Capturing an Outpost gives your team points over time and a new spawn location close to the fight, so the front line moves as Outposts change hands. The first team to 1,500 points, or the leader after 20 minutes, wins. The clip is jackfrags capturing an Outpost inside a building, then reinforcing it.
Reinforcing an Outpost your team holds unlocks more powerful team rewards in steps: first local UAV coverage, then a JLTV dropped from the air, and at the top a Light Tank delivered to your headquarters (Call of Duty). Holding ground is therefore worth more than chasing kills, since every reinforced Outpost brings the next reward closer. Activision has not published the exact points per Outpost or capture times as of Oct 25, 2026. The clip is jackfrags' match as a crate comes down by parachute and he then drives a tank through the streets.
The three maps
Imjin Farmland covers the rural outskirts of Hajin: open fields, waterways, scattered farms and a large mill, crossed by roads and rail lines that suit long sightlines, vehicles and assaults on strongholds. Wolves Stadium is the dense urban heart of Hajin around the Wolves Stadium, with multi-story buildings, transit lines, tunnels, rooftops and the hillsides around them. Forest is a wooded hillside between those two, with streets, off-road paths and the southern train tracks, and objectives at the hilltop guard tower, the gas station and the barracks (Call of Duty). The clip is jackfrags on a wooded map, passing a gas station and climbing a guard tower.
Imjin Farmland and Wolves Stadium were the two "purpose-built Combat Outpost maps" of the beta, both set within Hajin, the DMZ map (Call of Duty, Aug 21, 2026); Forest is new at launch. The beta guide spelled the first one "Imjin Farmlands"; the launch notes write Imjin Farmland. The full map list is on Multiplayer Maps, and the city itself on Hajin.
Vehicles and how to fight them
The Ground War maps are built for vehicles: Activision describes Imjin Farmland's roads and rail lines as suited to "vehicles and assaults on strongholds", and the JLTV and Light Tank arrive as Outpost rewards (Call of Duty). Activision has not published a full list of the vehicles on each map as of Oct 25, 2026. The clip is jackfrags driving a tank along wooded roads.
Several launch weapons and tools are made for them, per the Oct 19, 2026 loadout blog: the PILA launcher's missiles detonate on vehicles at any range, the JOKR locks on and strikes from above, the Proximity Mine can stick to a vehicle driving over it, Thermite does heavy damage to vehicles, and the Shock Stick sends them haywire. GamesRadar+ says the Signal 50 sniper rifle suits Ground War better than the small 6v6 maps; its Apex conversion adds incendiary rounds with more damage against vehicles and killstreaks. Launcher and equipment unlocks are on Weapons and Equipment and Field Upgrades.
In the beta and on Switch 2
Ground War: Combat Outpost joined the Open Beta on Saturday, Aug 29, 2026 (beta patch notes), as 24v24 on Imjin Farmlands and Wolves Stadium. The launch version is 32v32 on three maps.
The mode is on every platform. Nintendo Insider's Switch 2 review played Combat Outpost as a 64-player mode on Nintendo Switch 2; more on the port is on Nintendo Switch 2 Version.
