Wheelman is a Halo 3, Halo Reach, Halo 4, Halo 5: Guardians and Halo Infinitemultiplayer, Firefight and Spartan Ops medal awarded when the player, as the driver of a vehicle, has one of their passengers kill an opponent. In the first two games it is represented by a gold star with a tire on it. Writing on the tire reads 'ROAD KILL TIRES'. In Halo 4 it is represented by a white skull with a steering wheel on the forehead atop a blue circle and grey pentagon. In Halo 5: Guardians the skull and steering wheel are black inside of a yellow roadsign.
In Halo Infinite, the player must get ten assists in a match to gain the medal.
Usually, it is accompanied by the message, "Your driving assisted <player>."
The medal can be achieved easily with any map that has a Warthog, especially in a Big Team Battle match.
Keep moving. If you stop a Warthog, Mongoose, Prowler, etc. it is a sitting duck, and can be easily stuck or hijacked.
When playing a slayer game only have a driver and a gunner. Having a passenger most likely will give the other team a Triple Kill. Only have a passenger if it is an Assault, Oddball or Capture the Flag game.
The original design of the medal is very similar to the Wheelman Spree medals. This design was originally used to represent the Halo 2Roadkill medal.
It is in fact possible to get a Wheelman medal after someone sticks a player and then boards in a vehicle. Less common is filling someone up with needles or spikes and then getting in, as the time for the projectiles to explode is minimal.
