Tank Dropper

Tank Dropper is one of the the newest Halo 3 achievements that is gained by getting a kill while in Monitor mode in one of the Mythic Maps. Therefore, this is only possible to achieve in Forge. The most common way to get a kill in Monitor mode is to drop something on an opponent, such as a Fusion Core, or as in the medal's name, a tank. It is worth 25 Gamerpoints.

It is represented by a Monitor shown next to a dead Human, with three stars in between them.

Methods

 * 1) Start up Forge on . Go into monitor mode and spawn any vehicle or object and get an opposing player to stand still below you, and then drop it to splatter them; however, the best option is to spawn a Scorpion Tank, as this covers a much larger surface area, is heavier, and so is the easiest object to get a splatter with.
 * 2) Another way to do this is to stick a grenade to a person and quickly switch into monitor mode before it explodes.
 * 3) Yet another way is to sign on a guest on a different team; launch a rocket across a Mythic Map at your guest; and then switch to edit mode, before the rocket lands a kill.
 * 4) One more way is to hit an enemy with a large swinging object.
 * 5) Also it is possible to sign on a second player as a guest, get them in a vehicle and sell the vehicle with them in it, thus killing them instantly.

Note: The Killball does NOT count as your kill since it counts as "killed by the guardians."

Trivia

 * Currently, this is the only Mythic Map Pack multiplayer achievement that can be earned while offline.
 * You do not need to drop a tank to obtain this achievement. Swinging a Radio Antenna around wildly and hitting someone will likely kill them, earning the achievement.
 * One of the smallest things you can kill someone with is the traffic cone, albeit very difficult to align, but hilarious to watch. A video by Rooster Teeth on how to earn this achievement can be found below.
