Unable to defend against the deadly Panthers on vast, open battlefields, Estancian troops retreated to the urban labyrinth of Estancian cities. Familiar with the urban layout, Estancians hid inside city buildings and ambushed the incoming Omangans. Omanga’s campaign against Estancia had been raging for years, stretching conscription to the limit. To make matters worse, Omangan battle tanks and Panthers failed to exert their full strength in urban zones, sinking the Omangan campaign into dire crisis. To protect frontline soldiers and regain strategic advantage, Omanga developed its first transformable light tank, the Satyr P5C1. The introduction of the Satyr P5C1 provided a solid defense for the infantry and effectively ended the long-standing Omanga-Estancia Wars. The large-caliber artillery easily crushed enemy troops and annihilated buildings on both sides of the road, becoming the trump card in urban warfare.
