The invasion has begun, send forces to the surface and eradicate the defenders!
—Ingzan Admiral Se'nak during the Invasion of Hyaxnox
The WT-1 Walking Tank was a light walker based on the Espo Walker 91 and was used by the Imperial Army of the Ingzan-Bregaran Empire and the Hyaxnox Colonial Force of Hyaxnox Colony
In 1,028 ABY the Empire used these walkers against the Hyaxnox Republic, the performed well against the Hyaxnox Defence Force, but they were weak against rocket launchers, so WT-1 pilots decided to make rocket troopers priority targets since they did the most damage against the WT-1s. After seeing how weak WT-1s were against rockets and small arms, IBIAVY developed the WT-2 Walking Tank, this one was based on the AT-PT.
The rebel force Allied Armies Against Ingzan-Bregaran Imperialism also used captured ones, WT-1s were also found in use by the House of Dezendyan Security Force, which maintained security aboard Dezendyan ships and space stations.
