Drill Tank



The concept is simple, really. A tracked vehicle with a great big drill bolted onto the front. What it is varies. Theoretically, this may be intended as a mining and/or tunneling vehicle, and indeed, many of them do use them to tunnel beneath the earth. Others use them to break through walls and other barriers. Quite a few of them are used directly against enemies. There is an occasional variant in the form of a Drill Jet, which is exactly what it sounds like.

Given the status of drill with Super Robots, any Combining Mecha Super Robot has a good chance of having one of these as a component.

Subtrope of Tank Goodness. Often involves Fast Tunnelling

 * In Transformers Energon, one of Optimus Prime's mini-vehicles is a drill-tank. Oddly enough, when Prime combined with them for his Super Mode, the drill would be used as a leg, rather than an arm. A few episodes into the series, the animators realized this, and the drill switched to an arm from then on.
 * Drill-tanks are also the vehicle modes of several Transformers, including Galvatron from Beast Wars Second, and Menasor from Transformers Cybertron.

Literature
"It would be the greatest mining vehicle ever constructed: fifty feet long and fully mechanized, powered by compressed steam. It would boast three primary drilling and cutting heads, positioned at the front of the craft; and a system of spiral shoveling devices mounted along the back and sides would scoop the bored-through ice, rocks, or earth back out of the drilling path. Carefully weighted and meticulously reinforced, this machine could drill in an almost perfect vertical or horizontal path, depending on the whims of the man in the driver’s seat. Its precision would be unprecedented, and its power would set the standard for all such devices to come."
 * The dygos in The Pendragon Adventure, where they're used by the Rokador of Zadaa to make their Elaborate Underground Base home.
 * The "iron mole" that delivers David Innes and Abner Perry to Pellucidar in Edgar Rice Burroughs' Pellucidar series.

 * In the Tunnels series, the Coprolites use drill tanks to excavate the tunnels of their expansive civilization Beneath the Earth. One of the heroes later steals one to break through the walls of a reinforced bunker.
 * A 1946 short story, "The Last Objective" by Paul Carter, features very large subterrene drill tanks the size of oceangoing warships--"underground cruisers"--in a post-apocalyptic world in which the surface has been rendered uninhabitable by atomic bombs but the survivors continue to futilely battle it out underground.
 * Unfortunately we never actually see the device in action, but Dr Blue's "Incredible Bone-Shaking Drill Engine" is the 'title character' of Boneshaker, a Steampunk novel by Cherie Priest. A massive mobile drill created in 1860's Seattle to drill through the ice for the Russian government,

Live Action TV

 * The Drill Driver of Power Rangers Operation Overdrive, and its Super Sentai counterpart GoGo Drill. Far from the first, and probably far from the last.
 * GoZyu Drill from Kaizoku Sentai Gokaiger, the default form of GokaiSilver's personal mecha GoZyuJin. Technically speaking, it's actually a Drill Jet, but in practice it hovers low to the ground and generally acts like a Drill Tank (presumably because having it fly in every battle would make production costs skyrocket).
 * One of them is used in an episode of Eureka.
 * Tomica Hero Rescue Force has one in the form of the Rescue Drill.
 * The lead car of Kamen Rider Zeronos' Cool Train has a giant bull head that can flip around to reveal a drill.
 * Stargate SG 1 had an episode featuring one of these, built by aliens somewhere on the Diesel Punk stage of technological development. And designed by Jonas Quinn, in one of his few appearances after he left the main cast. It actually turns out to not work particularly well at a critical moment, and much tension ensues.
 * Space Sheriff Shaider calls for one from his Cool Ship when he needs to break into a fortified / underground enemy base. Upon making a breach, he fires a couple of missiles before disembarking and assaulting on foot. This cop doesn't believe in flashbangs.
 * In VR Troopers, they get one of these in the second season (when the Shaider footage starts being used.) Strangely, it seems every Evil Plan ever suddenly requires something to be made in one of these underground facilities before the facility is destroyed in precisely the same fashion as last week's.
 * The Mole in Thunderbirds is one of these.
 * A variant in Farscape with the drill-capable elevator on Katratzi.

Tabletop Games

Toys

 * Microtron, a caterpillar-tracked robot from the Micronauts/Microman toy-line was one of these, with a rotating drill-bit protruding from his groin area. With Micronaut "interchangeability", it could be reconfigured to more closely resemble a Drill Tank, with the drill where the head should be and large wheels instead of arms.

Real Life

 * Tunnel-boring machines.
 * And by extension, the tunnel driller in Red Faction. And yes, the drills here actually carve through stone.
 * The example from Avatar (particularly its way of movement) was also based on the tunnel-boring machine.
 * Subverted, it bores (like a file), not drills (like a, well, drill).
 * Heck, Subterrenes could theoretically drill tunnels and eliminate waste rock AND reinforce the resulting tunnels fast enough to act as transportation. However, only the Russians have ever been stupid enough to actually build a "Battle Mole", as the primary component was a nuclear reactor. Which broke down and killed the crew. Conspiracy Theories abound, however.
 * Mind you, that nuclear reactors are used (for the most part) safely and efficiently on almost all modern submarines and aircraft carriers. The concept only needed better engineering.
 * In 1938, the British, anticipating that World War Two would be an exact re-run of WW 1, designed and built a group of mammoth tanks, each weighing 185 tons, built for one purpose and one purpose only - digging trenches, in order to get that back-breaking labour safely mechanised. More cynical officers, whose reading of German strategy had convinced them that trench-building was futile, named these machines the TOG tanks, as "The Old Gang" of Colonel Blimps had ordered them built at masive cost. One was lost in France, and labelled useless scrap metal by its German captors; another two were used to build trenches and tank-traps around London in the event of German invasion.
