The F2 was propelled by four legs and could interact with its environment with a heavy grasping jaw. Within its head was located audio, video and olfactory sensors, as well as a motion sensor and Comlink for communication. The F2 was programmed with dedicated loyalty to its "masters," so much so that it was known to perform acts of courage to protect them from danger.
Compared to the MULE droid, the F2 could not carry as much cargo. However, the lack of a repulsorlift meant it was harder to detect. This made it popular with Alliance Special Forces for use on their missions.
