This unit appears to be a "Drone," which is similar to the military drones we are familiar with. This particular example seems to have the ability to repair damaged equipment. Dr. Shen and I believe it should be possible to capture and repurpose these for our own use in the field.
The "drones" we've disassembled seems to have a singular purpose: to repair the alien technology, including its robotic counterparts. Although they act as robotic medics, and lack any kind of offensive weaponry, we did discover a large explosive charge is located deep within the sub-structure it draws on as a power source. With this and several of the alien devices, I continue to be amazed by what their creators have been able to accomplish. Dr. Shen believes it may be possible to "hack" these drones, allowing us to utilize them for our own purposes. Further details as to this specimen's complete combat capabilities may be available in the field if targeted in the Unit Analysis View.
