Scout's Recon drone to be replaced by the Battery Drone - a slower unit (medium armor speed, has some acceleration like a vehicle), without the ability to fly, but it can use ropes. Works a lot like survivor - can be controlled by anybody nearby or by a comms user, though the drone doesn't have a morale. Has low sight range and no weapons. Model - Widow mine, with yellow light on top of it.
It's main ability is to build an unpowered battery, enabling to power up one turret or shredder; costs 5 supply and has a few seconds of constructing time. The drone then must remain static, on top of the battery to actually project the field - the battery doesn't do anything unless the drone is connected to it. While at it the bulb on top of it burns green. Can't build a battery near another power source, be it preplaced or one built by a drone; distance - 12 (most of the screen), or even more for a large power field source. Battery drone can also deconstruct the built batteries (Engineer can too).
It gets attacked by enemies, almost as often as a regular player without stealth, so it should be covered by a turret, or players while it moves around. Isn't very durable - 60 hp and 4 armor.
Scout can only have 2 drones at a time, each costs 30 supply and has 5 minute recharge time; it is also expensive to repair it. But if it gets killed, a toolkit user or Engineer can fix up its carcass, the bulb on the damaged drone glows red.
