Battlefields feature two key objectives, known as camps, that are key in plotting total battlefield control: Advanced Camps and Supply Camps.
Advanced Camps allow you to spawn your tanks in different locations, allowing you to drop in behind enemy lines for surprise attacks, or continue the advance.
Supply Camps reduce the re-spawn time of your tanks, allowing you to get back into the battlefield faster.
In order to receive the benefits of these camps, you will need to capture them. To capture a camp, you simply need to move your tank into its capture area and wait for the capture gauge to fill. The more allies stand in the capture area, the faster the capture completes. Enemies can enter the capture area and disrupt your efforts to secure the objective. Moving your tank from the capture area before its complete will cause the gauge to empty. In addition the benefits listed above, when a Forward Base is captured, allied units will slowly regenerate health while in its vicinity.
