Kalran: Tales of the four nations/Bulldog

Tactical analysis

 * Get off my fucking lawn: The Bulldogs, another Shepherd variant, main "attack" is to violently push the target unit away from itself. While this has obvious applications in the field of "get out of my base", it can theoretically be used to boost friendly units a bit in the desired directions. It may be more useful than it sounds, given that most Volksgards vehicle are a fast as a turtle. And its huge plow can crush infantry, light vehicles, and lesser structures, landmines, and tank traps with ease


 * Are you even fucking trying: The Bulldogs giant plow, and passive void field also forces enemy attacks going past them to hit them instead, where its superheavy armor pretty much deflects it. Lead in with a few Bulldogs, and the rest of your army will make sure the enemy never gets the chance to switch targets


 * Out of my fucking way: Normally the Bulldog isn't the quickest vehicle in the Volksgard. To address this, an industrial-strength turbocharger was installed substantially increases top speeds, during which they unveil the vehicles grinder teeth are revealed, which rips apart the targeted vehicle or structure to repair its hull. Note that the turbo speeds will further weaken the Bulldogs sides and rear to vent the heat generated and they lose a good chunk of maneuverability


 * Wait a fucking second: Note that the Bulldog has a rather slow speed and its attack deals no damage and limited to melee range. And while practically indestructible from the front its slow speed makes it vulnerable to flankers

History
(Note: half of the lore is currently in progress)

To this end, they retrofitted one of the Shepherd tanks, replacing the turret and every space but the drivers with high-speed pistons and a large, almost damage-proof prow. During one of the junkmen's test runs, a worker was nearly beheaded by a flying boulder. He immediately and furiously demanded to know what was going on, and the rest, as they say, is history.

A military variant, alongside a more friendly civilian variant, was planned, with its designer leading the project. A workshop was set aside for the purpose of trimming up and properly "armoring up" the machine. A few weeks later, a machine emerged from the workshop, battle-ready and armored from top to bottom.

Unique for a tank it only requires one driver, with the spaces for ammunitions, crew, and turret replaced with either armor or engines, with a void generator built so that any enemy projectile trying to go past them are redirected to it's indestructible plow, and a special grinder behind the plow, using this with void magic to rip apart segments of debris that melds to weak sections of the armor, effectively regenerating hull strength in the midst of a battle. But it lacked any proper weaponry, due to optimizing it's toughness to the point that there wasn't even any space for ammunition for a HMG. Said drivers are also known for being rather ornery.

The mission, as it stands, is to remove unwanted obstacles from anywhere the Volksgard sees fit. This incredibly ambiguous statement allows the Dwarves to deploy the military Bulldog pretty much however they want. The massive prow allows the Bulldog to function as the "moving wall" of their general doctrine. If it gets in close enough to an enemy vehicle, it can send it flying backward with a quick piston-powered shove of the prow.
