Proximity Scan is a specialization available to all vehicles. When equipped, enemy infantry in the immediate area are marked on the minimap.
Like other sensors, the game actually checks to see if the enemy is within range along the XY plane, ignoring height. Visualized, the sensing area would form a standing cylinder with the vehicle at its center.
Proximity Scan can help you greatly in Ground Vehicles. It allows you to spot enemies approaching your vehicle, so you can engage C4 carrying units before they are able to harm your vehicle or quickly retreat before they can plant their explosives. Also attacking a flag is much more safe; you can easily pick the enemies one by one, and help your team.
Air vehicles however recieve much less benift with it being practically useless on jets as the player flys at too great a speed to get any use out of it (it can help your teammates however). Helicopters may recieve slightly more use as a hovering helicopter can detect nearby hidden enemies and if forced to land can detect any players aproaching their vehicle.
