I-C4a combat construction droid

The I-C4a combat construction droid was an autonomous construction droid manufactured by Veril Line Systems for the Galactic Empire's Imperial Corps of Engineers. The droid possessed a fabrication system that allowed it to produce slabs of building material with which to create structures. While a majority of I-C4a units were owned by the Imperial Army, the construction droids also fell into civilian or Rebel Alliance hands, developing personalities when not subjected to the Empire's frequent memory wipes.
