The documents we've found identify this derelict, centuries-old hulk of 10-feet tall assault droid as 'Xenforcer'. It was manufactured by UAC. We don't have the slightest idea how to repair this imposing machine, but we can salvage it for Power Armor parts, superconductive wire and a whole lot of assorted junk. Neither the machine's thinking circuits or reactor once used to power it survived in any useable shape.
