The B1 battle droids were the top of the line battle droids around the time of the Naboo Crisis. Upgrades were made, but the B1 battle droid still remained the most prominent force through until the end of the Clone Wars. B1’s came in two colors, beige and sand red. Although the sand red design was used predominately on the battlefields of Geonosis, they did see action aboard the starship, Invisible Hand. At the end of the Clone Wars, the B1 battle droid models were forced to find other fields of work, the more popular were mechanics, piloting, and engineers.
