The All Terrain Heavy Enforcer, often shortened to AT-HE, represented a specific walker design within the AT-series. Its development occurred in the years after 22 BBY, spurred by the favorable reception of Rothana Heavy Engineering's All Terrain Tactical Enforcer. Distinctly, the AT-HE possessed greater weight compared to the AT-TE, featuring an elevated hull that provided protection from mines and enhanced the targeting capabilities of its energy-based weaponry.
Within established Star Wars canon, the All Terrain Heavy Enforcer received recognition through its inclusion in the 2018 reference publication, Star Wars: Complete Vehicles. Intriguingly, the walker initially appeared in the Star Wars Legends timeline. Its initial reference was in the 2002 reference work titled Star Wars: Attack of the Clones Incredible Cross-Sections, authored by Curtis Saxton.
