In Star Wars: Legion, Battle Forces represent groups of units that fought side by side in the Star Wars galaxy. These forces are themed around unique sub-groups and can range from a ragtag group of Mercenaries to the main invasion force of the Empire.Battle Forces provide players with an alternative way to build and field an army. Each Battle Force has its own list of specific units that it is allowed to field, its own Rank requirements for both standard and Recon armies, and its own special rules, which may affect how that Battle Force is built, set up, or plays.
