Clone Commander Gree, designation 1004, led the Elite Corps of clone troopers during the Clone Wars. He saw deployments on such heated battlefronts as Kashyyyk. Gree himself wore camouflaged armor to better blend into jungle surroundings. Though a faithful commander who carried out the Jedi's orders, Gree was ultimately loyal to the Republic. When Chancellor Palpatine enacted Order 66, Gree understood it was a worst-case scenario contingency -- the Jedi had betrayed the Republic, and were therefore dangerous enemies of the state.
Gree was Luminara Unduli's appointed clone commander. The two would work together during the Kashyyyk campaign at the end of the Clone Wars.
When Nute Gunray was captured by the Republic and held aboard the cruiser Tranquility, Gree was part of the security contingent guarding this valuable prisoner.
Commander Gree was unable to stop the treacherous Senate Commando Captain Argyus from freeing Gunray from Republic captivity.
Clone Commander Gree tried to kill Jedi Master Yoda once he received Order 66 from Chancellor Palpatine. Gree did not get very far on that assignment.
Stationed on Kashyyyk, Gree coordinated combat strategies with General Tarfful, the ranking Wookiee officer defending the tree villages from Separatist attack.
