Research UAV intelligence support technology and the build Air Field to perform Recon missions. Once you've done that, purchase several Recon Drones ( MQ-11B ). Send Recon Drones to the other player's Base to gather intelligence. Your reports will inform you on your recon mission's outcome and collected information. Recon missions allow you to get full information about the number and type of Troops in other Bases and about the amount of Resources you can raid from that Bsse. Your Recon Drones can be defeated by the reconned Base's Drones while performing the mission.
Recon missions can be performed in 3 ways:
From the Map:
Click «Map» in your Base. Position the cursor over the Base you want to recon. Choose «Recon» on the Base menu.
From inside the enemy's Base:
Visit the Base you want to recon. Choose «Recon» from the «Actions» menu.
From the Command HQ:
Go to the Command Center. Open the «Send» tab. Choose «Recon» from the action list. Click «Recon».
