{{Quotation|Day 1 of the '''[[Mann vs. Machine update]]'''|We don't know what this thing is, but it's big as hell, looks unstoppable, and it probably runs on human blood. We're just guessing that last part, because it's usually covered in it.}}

'''Tank Robots''' (referred just as '''Tank''') are large bomb-carrying [[Robots|machines]] that arrive with the robots in [[Mann vs. Machine (game mode)|Mann vs. Machine modes]]. They carry no offensive weapons and thus have no direct way of harming the player. They can take an extreme amount of damage before they are destroyed, far more so than any other robot. The [[Administrator]] announces the entrance, progress, and destruction of each tank.

After entering the map, tanks slowly travel along a set path to the bomb hatch before deploying their bomb and ending the round. This path is unique to each map and may differ from the path of other robots in the wave, if any. They have their own bomb, independent of the one carried by the other robots, and in waves with tank(s) and bomb-carrying robots, both the tank and the robots must be destroyed to complete the wave.

Tanks are immune to all effects outside of damage and critical hits; they can only be stopped via destruction. They cannot have their movement interrupted or [[slow]]ed; standing in front of one will simply push the player away for no damage, while players that cannot be pushed away due to walls or props are crushed to death, and [[building]]s in the way are destroyed. They cannot be [[burn]]ed or soaked by [[Jarate]] or [[Mad Milk]], they do not give [[metal]] to [[Widowmaker]]s, they cannot be [[sap]]ped or marked for death, they do not give health to players buffed by the [[Concheror]], and they have no [[headshot|heads to shoot]] or [[backstab|backs to stab]]. Finally, they resist 75% of [[miniguns|Minigun]] damage, severely reducing a Heavy's damage output against it.

Tanks have a health meter below the "robots remaining" display on the [[HUD]], and as they are damaged, they will acquire bullet holes and cracks and lose parts, like the covering on their treads. The final tank of a mission has distinctive white stripes; this does not correlate to any of its properties.

== Elimination ==
When a tank is the only robot in the wave (excluding support-class robots like Snipers), it should be focused on by all players until it is destroyed. [[Kritzkrieg]] Medics and [[Canteen]]s are extremely effective when paired with sustained high-damage classes like Pyros and Soldiers, or when used with Demomen using his Grenade Launchers and Stickybomb Launchers. [[Wrangler|Wrangled]] Sentry Guns also deal massive damage to tanks, but may have to be relocated once the tank passes out of their range or if they're in the tank's path. As well, the hitbox of the tank is very large, making weapons with "bullet spread", such as the [[Frontier Justice]], effective even at medium-long range.

If a tank arrives with other robots, especially giant robots, consider killing the robots first, as tanks do not deal damage and can usually be dealt with after the regular robots if they have not traveled more than halfway. On many missions, it is very beneficial to designate one or two players as "tank-killers," usually Pyros, Demomen, or Soldiers, to follow the tank while the rest of the team contains the bomb. The tank's resistance to Minigun damage encourages team balance by severely punishing teams that rely on an excessive number of Heavies.

After arriving at the bomb hatch, the tank will take a while to deploy its bomb, so the team still has time to destroy it.

==Trivia==
*When spawned on a Payload map using a plugin, the tank will follow the cart's track backwards, exploding upon hitting the cart.
==Bugs==
*Tanks that spawn after another tank in the same wave may be announced by the [[Administrator]] as being halfway through the map. This usually happens when the third Tank in a wave spawns, provided both preceding Tanks have been destroyed already.
