Trade Federation security droids fulfilling their most common role as guards on capital ships carried the standard weapons (E-5 blaster rifles) used by similar models. The ubiquitous model served as the basis of the B1 battle droid used in the Trade Federation's Droid Army, although the latter model had less complicated programming. However, the targeting and coordination of the security droids was little better than that of their cousins, and often failed to consistently hit their target.
