Star Wars Battlefront II Clone GALACTIC MARINE Figure 187th Attack Battalion TRU
The 187th Legion, also known as Mace Windu's Attack Battalion, was a legion of elite clone troopers that served under High Jedi General Mace Windu and an unidentified clone commander. They were distinguished by the purple markings on their armor which matched Mace Windu's hurrikaine lightsaber crystal in color.
Siege of Dantooine
Specifically trained to be capable of supporting their High Jedi General in battle, the 187th Legion participated in many strategic missions throughout the Clone Wars. At the onset of the Clone Wars, immediately after the Battle of Muunilinst, the Confederacy of Independent Systems began using the planet of Dantooine as a staging ground against the Republic. Learning of this Separatist presence, Master of the Order Mace Windu dispatched an army of clone troopers to take back the planet. During the battle, the 187th Legion secured an important victory for the clone army, which allowed the Republic to take control of the planet.
Battle of Coruscant
During the final stages of the war, the Confederacy of Independent Systems launched a full scale invasion on the Republic's capital. During this battle, the droid army began an assault on the Jedi Temple. The 187th Legion, alongside their Jedi General, fought to protect the temple.
