224th

The 224th Infantry, commonly referred to as the 224th, was a Grand Army unit of clone troopers under the command of Clone Commander Trigg and Jedi General Zay Arlenn during the Clone Wars. Troopers assigned to the 30th were distinguished by the olive-green markings on their armor. Composed of smaller units such as the Mud-Jumpers and Ghost Squad, the overall 224th had developed a reputation for their numerous victories on the front lines.

Throughout the Clone Wars, the clone soldiers of the 224th fought in numerous battles across the galaxy, most notably the Republic attack on Quil'ages in 19 BBY. During this battle, Supreme Chancellor Palpatine issued Order 66, a directive to carry out the execution of traitorous Jedi Generals. Unlike most of the soldiers in the Clone Army, Commander Trigg disobeyed the directive—having removed his inhibitor chip months prior—and was taken into custody by his own troops after failing to apprehend General Arlenn. Shortly afterward, the Republic was reorganized into the Galactic Empire.

The 224th, and other clone units, were later assimilated into the Stormtrooper Corps. In 10 BBY, the remnants of the 224th were sent to Nar Shadaa to assist in the apprehension of two fugitives, later revealed to be Zay and Trigg in exile. Their ultimate failure resulted in the decimation of the unit permanently.
