CC-3636, nicknamed "Wolffe," was a veteran clone trooper commander in the Grand Army of the Republic who served with Jedi General Plo Koon during the Clone Wars. The leader of the 104th Battalion's famed Wolfpack squad, Commander Wolffe proved to be tireless in his efforts against the Confederacy of Independent Systems, displaying an affinity for strategy. In 22 BBY, on his first mission with Koon, Wolffe served on board the Jedi Master's flagship, the Triumphant, when Koon led a task force to eliminate the Separatist warship Malevolence. While confronting the Malevolence in the Abregado system, however, all of the Wolfpack was eliminated, save for Koon, Wolffe, and troopers Sinker and Boost. The four were rescued by Jedi General Anakin Skywalker and his Padawan, Ahsoka Tano, and Wolffe had his unit adopt new clone trooper armor in honor of his fallen comrades. Refusing to let the loss of the Wolfpack deter him from his service, he inspired loyalty amongst his men.

Wolffe's loyalty to the Jedi put him at odds with the ambitious Major Kendal Ozzel during the Battle of Khorm, in which they participated alongside Generals Koon, Kit Fisto, and Tauht. Though Wolffe lost his right eye in a fight with the Dark Acolyte Asajj Ventress, the Republic defeated the Separatists and liberated Khormai slaves, thus securing the planet's repositories of rare agrocite ore for the Grand Army. Although scarred and forced to wear a cybernetic eye replacement, Wolffe continued his military service to the Republic, undertaking several key rescue missions with Koon to Felucia, Vanqor, and Lola Sayu. He even joined Koon in challenging General Grievous during the Second Battle of Felucia and the following Mission to Iceberg Three. He personally oversaw a supply mission to the groundquake-devastated planet Aleen, assisted in liberating Togruta slaves from the Zygerrian Slave Empire on Kadavo, and took part in a 104th mission that recovered the lightsaber of the late Jedi Master Sifo-Dyas.
