What B1-series Battle Droids lack in durability and combat prowess they make up for in ease of production. The sheer number of droids the Separatist Alliance can produce has allowed them to strike quickly and decisively across the galaxy with overwhelming force.

This Star Wars: Legion B1 Battle Droids expansion contains: 1 B1 Battle Droid Unit Leader, 12 B1 Battle Droids, and 2 B1 Battle Droid heavy.
