DCS: Combined Arms gives you control of ground forces during the battle. Use the strategic Command Map to move ground forces, set artillery fire missions, and control the ground battle. Assume the role of a Joint Terminal Attack Controller (JTAC) and designate targets for close air support aircraft, or directly control an armor vehicles or air defense weapons and engage enemy forces.
Play DCS: Combined Arms as a real time strategy game, a first person armor warfare simulation, or direct the ground battle from the cockpit of a DCS aircraft like the A-10C Warthog, Ka-50 Black Shark, or P-51D Mustang.
DCS: Combined Arms supports both single player and multiplayer gameplay. When in multiplayer, different players can take on different roles such as artillery commanders, tank commanders, pilots, JTACS, etc. DCS: Combined Arms allows you full control of the battle. All roles can be changed dynamically during the battle.
A new function that Combined Arms introduces is the ability to set ground command roles and the number of players that can take each role (for multiplayer). Roles include:
Mission designers can choose which of these roles to include in a mission and how many multiplayer slots for each one.
In addition to the ground command roles, players can also direct ground forces from the cockpit of their DCS aircraft.
The Command Map is the strategic interface that allows you to move ground forces, set formations and Rules of Engagement (ROE), plan indirect fire missions (artillery and rocket launchers), and view all friendly forces and detected hostile forces.
The Command Map uses Fog of War and will only display hostile units that are first detected by friendly forces. This makes the need for reconnaissance essential in Combined Arms.
When routing ground forces, you can either set multiple waypoints to reach an end destination, or command units to follow roads.
The Command Map, allows Combined Arms to be played as a Real Time Strategy (RTS) title.
For those that want to participate in the ground battles from a 1st person point of view, players can select most friendly ground units (most armor and visually guided air defense systems) from the Command Map, press the Command Unit button, and occupy that unit in the 3D world. Tanks, infantry fighting vehicles, armored personnel carriers, anti-aircraft artillery, and short-range SAMs can all be controlled. Many vehicles have multiple types of weapons like machine guns, main tank guns, and anti-tank guided missiles; all of which can be controlled.
When in a 1st person command view, the player can also order the other ground units in their group to specific locations.
