All USA ground vehicles, with the exception of the construction dozer and Sentry Drone, could be upgraded with a Scout Drone, Battle Drone, or Hellfire Drone. Each vehicle could only have a single drone assigned to it.
The Scout Drone was a stealthed reconnaissance drone tied to a parent vehicle. It was unarmed, but was equipped with advanced scanners which increased the sight range of the parent vehicle while revealing stealthed units.
The Battle Drone was a utility drone tied to a parent vehicle. It was armed with a light machine gun and could repair its parent vehicle.
The Sentry Drone was a larger reconnaissance drone built from the War Factory. It was stealthed, had a large sight range, and was able to detect enemy stealth units. It could be upgraded with a 20mm autocannon, making it effective against enemy infantry (especially stealthed ones), as well as light vehicles.
The Spy Drone was a stealthed reconnaissance drone which was available with a Rank 1 General's Promotion. A single drone could be periodically deployed anywhere on the map, after which it remained in the area while providing sight radius and detecting stealth units.
