Surveillance Sweep

Accurate intelligence was crucial to win a war. The Allies know this, and introduced the Surveillance Sweep ability. Allied Commanders with enough clearance can access this ability in their Top Secret Protocols menu on their EVA Interface. A group of supersonic spy planes will sweep in and explore the designated area for enemy forces, including any disguised or stealth units.

Instructions to Allied Commanders
To use this ability: click on an area on the map (A) where you want to explore, then click on another spot (B) to mark the flight path of the spy planes. The planes will arrive and sweep the area from A in the direction of B.
