Use contextual producers, visible prerequisites, and the research path shown in the command deck. Nothing essential depends on a separate catalog.

LOGISTICS

Haulers collect finite supply from physical nodes and return it to Supply Depots. Select a Hauler to see its route. No population cap exists. Supply, infrastructure, terrain, and production time determine army scale.

INFANTRY

Rifle Teams control infantry. Spear Teams threaten armor and aircraft. Signal Teams reveal and designate. Eligible infantry may enter marked neutral structures and fire from legal apertures.

SUPPORT

RepaiRoamers repair friendly ground vehicles and structures. Barracks, Vehicle Bays, Command Cores, and Helipads service compatible units within their capacity.

AVIATION

Helipads support rotorcraft and may expand into Airports after research. Fighters contest the sky. Bombers strike ground targets. Aircraft require physical service and rearm infrastructure.

TOUCH

Tap-Friendly mode supports tap commands, double-tap Guard, drag selection, two-finger camera movement, pinch zoom, and a long-press command menu. Every command remains available through visible buttons.

CAMERA

Move with WASD or Arrow Keys, use screen edges when enabled, or drag with the right or middle mouse button. A short right-click remains a contextual tactical command. Wheel zoom follows the pointer. Hold Shift while panning for rapid theater traversal.

INTELLIGENCE

Black is unknown. Dark gray is remembered. Broken hostile markers are detected contacts. Clear ground is current visual observation. Shape remains meaningful even when optional colors are enabled.

ESCALATION

Research unlocks fieldworks, artillery, air defense, advanced armor, Airports, jets, bombers, and faction strategic weapons. Infantry may Dig In after Fortified Fieldworks is complete.

MISSION

Destroy the opposing command structure. Keep your own online. Scout resources, occupy outposts, protect roads, and attack logistics when a direct fight is unwise.
