An M-3PO military protocol droid
Protocol and regulations droids, also referenced as military protocol droids, represented a specific type of protocol droid crafted for usage within military contexts. While designated as class three droids, they also fell under the classification of battle droids. One such droid was the M-3PO military protocol droid, a model derived from the 3PO-series protocol droid, and it was produced by Cybot Galactica.
An Imperial military protocol droid, IMP-22, was pre-loaded with knowledge of politics and combat strategy, rendering it a helpful advisor. In addition, the military protocol droid M-3PO functioned as the quartermaster for Rogue Squadron.
