When Tranquility suddenly came under attack by Vulture droids, the captain of the Star Destroyer alerted Clone CommanderCC-1004, nicknamed "Gree," that Droch-class boarding ships were approaching. As the boarding ships neared the Tranquility, Gree notified Green Company of the threat, ordering them to repel the enemy. Green Company ran toward the Tranquility's hangar to prepare for the oncoming attack. Meanwhile, the boarding ships have breached the hull and opened their main doors. B2 super battle droids dropped down into the Tranquility hangar and engaged the clone troopers. As the clones took cover behind crates, Green Leader contacted Gree and reported about the super battle droid attack. The clones struggled to fight back, but the droids, led by a super battle droid commander, dismantled the Republic force. Hiding behind a crate, Green Leader warned Gree that the droids were heading his way and that his squad needed reinforcements. However, a super battle droid spotted the clone and instantly killed him with a blaster shot.[3]
A loyal clone trooper, Green Leader obeyed any direct order that was given to him by his commanding officer, Gree. The clone, along with the rest of his men, was concerned about the success of their mission, and struggled to stop the Separatist attack. Green Leader also remained level-headed under pressure, contacting Gree to alert him of the dangers that Green Company was facing.[3]
