The principal battle tank of the Grand Army of the Republic, the All Terrain Tactical Enforcer features six articulated legs for propulsion. The legs are low to the ground, which reduces the walker's top speed but does provide it with increased stability. The body of the walker consists of two armored halves connected by a flexible sleeve that increases its mobility on the field. The walker is truly all terrain, able to climb sheer surfaces and survive in the vacuum of outer space. The front of the walker is lined with four ball-turret laser cannons, while a single heavy projectile cannon is turret-mounted on the vehicle's dorsal surface. Its rear fire arc is protected by a pair of laser cannon turrets. Though the walker's armor can easily deflect small arms fire, tanksmasher rockets can pierce an AT-TE's armor and destroy its complex propulsion mechanisms.

Clone Commander Wolffe (clone designation CC-3636) served under General Plo Koon in the Clone Wars, as commander of the tight-knit unit known as the Wolfpack. A seasoned and battered combatant, Wolffe has witnessed some of the worst the war has to offer. Early in the Clone Wars, he lost his entire command when Master Plo's flagship, Triumphant, was destroyed by the despicable General Grievous. Despite such tragedy, he fights on bravely, proudly brandishing his battle scars and instilling loyalty among his men.

An elite clone commando thought lost at the grueling Battle of Sarrish, CC-5576-39 survived a shuttle crash that left him stranded on the distant world of Abafar, stripped of memory and identity. He was found and rehabilitated by Mr. Borkus, and unscrupulous diner owner from the dusty town of Pons Ora. When the Republic agents of D-Squad discovered Gregor, they rekindled his memories of duty, service, and honor, and the commando reclaimed his armor and fought to a spectacular finish to ensure D-Squad carried out its crucial mission.

Clone Captain Rex served the Republic during the Clone Wars, often taking orders from Anakin Skywalker and Ahsoka Tano. He viewed military service as an honor, and he always completed his mission. Fond of using two blaster pistols at the same time, Rex customized his armor with distinctive blue markings. His loyalty to the Republic and his Jedi Generals was absolute, but even this dedicated veteran soldier found himself plagued by doubts as the Clone Wars claimed more lives and brought ruin to more worlds.

A dusty and remote planet known for it's salty plains, Seelos was the home of Clone Captain Rex, and Clone Commanders Wolffe and Gregor during their retirement. A backdrop of distant blue mountains made up Seelos' landscape as the clones traveled the harsh terrain in their modified AT-TE hunting Joopas below the planet's surface.

A worm-like beast with a crown of bright red eyes, the joopa makes its home deep below the crust of the planet Seelos. The creature's absence of teeth allows it to swallow its prey whole, most notably Lasats, a particular favorite meal of the joopa. The clones Rex, Wolffe and Gregor, however, attempted to catch joopas for their own nourishment, using Zeb as their bait. A single joopa could feed the crew for an entire year.
