Unidentified B1 battle droid 2 (Munificent-class star frigate)

"The Republic base is still transmitting the all-clear signal. But for some reason our commando droids are still not responding."

- The droid speaking to Grievous.

A B1 battle droid was stationed on the bridge of General Grievous's Munificent-class star frigate around 21 BBY.

History
During the Battle of the Rishi moon, this battle droid informed Grievous that the captured Republic base on the Rishi moon was still transmitting the all-clear signal, but the squadron of BX-series droid commandos who captured the base were not responding for some unknown reason. Grievous then ordered the droid to send reinforcements to the moon to investigate the problem. Later, the droid informed Grievous that the Rishi moon base was destroyed, and was ordered by him to take the ship away before Republic reinforcements arrived.
