Kalran: Tales of the four nations/Bombur Gauss Cannon

Tactical Analysis

 * Big gun on concrete: Nothing more than the cannon of a Doberman mounted on a bunker, the Bombur serves to guard Volksgard bases against armoured assaults. With its 200mm cannon well suited to cracking open the armour of main battle tanks
 * Rocket power: Unlike the Doberman. The Bombur fires rocket-assisted shells in place of conventional shells. Thus their range is longer than most anti-tank defences, though artillery still edges them out, barely
 * Vertically Challenged: Of course, the 200mm cannon is limited to right and left traverse, which means that it can't be used as indirect fire artillery, nor can it fire at aircraft. Its AP shells aren't particularly well suited to long-range bombardment or anti-air work anyways. And infantries are small and nimble enough to avoid being hit by the large armour-piercing shells. As a result, it doesn't fare nearly as well against other types of targets
 * Armour-piercing: By activating their Defense Bureau and gaining heightened clearance levels, the cannon can be upgraded will be upgraded with prototype autoloaders, penetrating tungsten rounds, and enchanting their rounds so that vehicles hit will be slowed

Trivia

 * Its design is based on the german 88m flak cannon and tank turret bunkers, taking its name off the dwarf from the hobbit.
 * Its role is based on the cannon turret from rise of the red and command & conquer.
