BX - series droid commando BX - series droid commandos , also known as commando droids , were advanced battle droid s used by the Confederacy of Independent Systems during the Clone Wars . Characteristics . BX - series commando droid s were advanced , sturdier versions of B1 battle droid s . They were programmed with improved combat tactics and battlefield awareness and equipped with glowing white photoreceptor s . Captain s and other high - ranking commando droids bore white identifiers on their heads and chests . Due to a more compact head size than the B1 , commando droids could don Phase I clone trooper armor for infiltration missions . Their heavy armor improved durability and allowed them to withstand several direct hits from standard - issue clone blaster s . Additionally , commando droids were extremely agile , acrobatic , and were able to move and react much faster than a standard battle droid . They were even able to continue fighting after having their legs sliced off with a lightsaber , in contrast to standard B1 battle droid s that could be defeated simply by knocking them over . For improved infiltration capabilities , commando droids were able to alter their voices in order to imitate clone troopers . However , their awkward movements in the armor and atypical responses to orders ( usually " roger roger " , a common battle droid response ) meant that observant individuals could see through the ruse . Commando droids were also shown to be quite strong as one was able to lift a clone trooper captain by his neck . Despite their numerous improvements over rank - and - file B1 and B2 battle droids , their production costs proved to be prohibitive for anything but small - scale manufacturing . History .
