UNW-A01 was heavy humanoid-like droid design which was used as a base for the production of various droid models - both for military and civilian purposes - by different droid manufacturers. Full production ID for this design was bmf_underworlddroid_a01_v01. Like with most humanoid-shaped models, manufacturers were allowed to install wide array of internal weapons, systems and protective shileds, while droid itself was capable of using most types of blasters, rifles, heavy autocannons and melee weapons.
