"Remote controlled UGV with a powerful airburst turret."
The Wheelson is a killstreak in Call of Duty: Modern Warfare. It is a remote-controlled drone armed with a powerful automatic grenade launcher with unlimited ammunition, and is small enough to go through most doors and move through tight spaces with ease.
When used, the Wheelson instantly spawns in front of the player. The player can see how much fuel (active time) and health it has on its GUI.
