The set was originally released via Entertainment Earth. A 6-inch figure of a 442nd clone trooper was released in late 2016 with three other troopers: one from the 212th Attack Battalion, one from the 501st Legion, and a clone shock trooper. The 442nd Siege Battalion first appeared in merchandise created by Hasbro Inc. Afterward, the battalion took part in the execution of Order 66.

Fighting alongside Jedi General Plo Koon, who was dispatched to coordinate the 442nd's siege, and his wingmate Captain Jag, the battalion secured a victory for the Republic. In the year 19 BBY, they were deployed to the planet Cato Neimoidia in battle against the Separatist forces there. The unit fought alongside the 212th Attack Battalion and Mekedrix's company during the Battle of Abrion Bridge around 22 BBY. The 442nd Siege Battalion was created to serve the Grand Army of the Galactic Republic during the Clone Wars, against the secessionist Confederacy of Independent Systems. Proficient in besieging enemy fortifications, they were equipped with vehicles such as All Terrain Reconnaissance Transports and Infantry Support Platforms that also featured green-colored markings. They were typically equipped with DC-15A blaster carbines. Members of the 442nd sported phase I clone trooper armor, and later phase II clone trooper armor, decorated with bright green markings. Clone trooper officers served in the unit. The 442nd Siege Battalion was an armor battalion of clone troopers in the Grand Army of the Republic, composed of four companies with 144 troopers in each.
