The Order of Battle represented the structured arrangement of soldiers within a military organization, a synthesis of diverse unit levels converging to create a unified fighting force.
This terminology found particular relevance when discussing land-based forces, notably in the context of the Grand Army of the Republic and its successor, the Imperial Army. During the Clone Wars period of the Galactic Republic, it was initially referred to as the OrBat, later becoming known as the OB within the Galactic Empire during the Galactic Civil War.
Within the Imperial Navy, the Order of Battle defined five distinct fleet structures: line, squadron, systems force, fleet, and sector group. The Flight Branch held the authority over the Navy's Order of Battle composition. A comparable Order of Battle system was also employed by the Stormtrooper Corps.
The clone trooper known as Green was assigned to these units:
