An artillery mobile suit introduced in the earliest stages of ZAFT's Earth invasion, the TFA-2 ZuOOT was not based on space suits like the mobile suits derived from the ZGMF-1017 GINN, but on worker machines used for construction in space. The ZuOOT was heavily armed, with a pair of twin cannons on its shoulders, a pair of twin secondary cannons on its left forearm, a handheld heavy assault machine gun, and four chest-mounted small caliber Vulcan cannons for close-range defense.

The ZuOOT can transform between a humanoid MS Mode and a Tank Mode, with the latter providing greater stability while firing its cannons and enabling better movement capabilities across certain terrains such as deserts. Due to its limited mobility and poor close combat capabilities, the ZuOOT was more like a movable gun turret than a true mobile suit, and it was used mostly to provide fire support from the rear. Like the GINN, the ZuOOT has a crest-shaped sensor array on its head, above the mono-eye, and this allows for real-time battlefield information to be displayed in the cockpit.
