Heavy Siege Breaker
The ZGZ-108 Zugzwang is a slow moving, mobile siege breaking platform. It's sole purpose is to dismantle hardened defenses and to expedite the occupation or annexation of cities. With only five superheavy sabot shells, twin cruise missiles, and limited anti-infantry and armor reloads, the Zugzwang is always found near supply vehicles. Support crews are trained specifically for efficient reload sessions, often clocking in at under a quarter of an hour delay between bombardments.
There are no tacticals used by any military that can withstand the kinetic force of even a glancing hit by its primary cannon, making the presence of a Zugzwang on the battlefield a looming threat for any rival force.
Although unable to be drone controlled and requiring a two person crew for full functionality, the Zugzwang does possess large, kinesthetically trained and programmed hands capable of lifting massive chunks of rubble and debris to assist in urban engineering efforts post combat.
