One of the few two-seat E-frames in the Exofleet, the RA-678 Rapid Assault was optimized for ground combat. It was equipped with an impressive array of weaponry and battlefield surveillance devices. Lt. Nara Burns and Marsala shared one of these before Burns' promotion. Their Algernon Upgrade was a cloaking device. (Even for Algernon, it is impossible to mount one on an object any smaller).
The Neo Sapien equivalent was the Troop Transport E-frame.
