Rebel commanders may be undermanned and underequipped, but they more than make up for this with resolve, tenacity, and sheer force of will. Leading by example, it's not uncommon for Alliance officers to wade into the thick of battle alongside their troops. When leading troops with specialized training, they can provide invaluable support to Rebel ground operations.
The Rebel Specialists Personnel Expansion for Star Wars: Legion contains four finely sculpted Rebel specialist miniatures, along with new unit, upgrade, and command cards that give you the power to field a generic Rebel commander and add troops with specialized training to other units in your army. Among them, you'll find a communications specialists, a medical droid, and an astromech droid, opening up even more tactical possibilities in your struggle against the Empire.
