Although I'm sure you can make the connection yourself, we've designated this particular specimen as a "Floater." The Research team is continuing in its efforts to determine how the aliens prevented the organic tissue from rejecting the mechanical components, as they seem to work in perfect harmony with one another.
As frightening and vicious as this species is on the battlefield, it is hard not to feel some sympathy for them on the dissection table. The specimen has been subjected to extensive biomedical modifications, some of which were undoubtedly quite painful and intrusive. The combination of living tissue and mechanical components gives the creature the look of a cruel, half-finished experiment. Most of the subject's internal organs have been replaced with a mechanical life support system that mimics their original functionality.
A rather conventional propulsion system has been grafted onto the subjects torso, although the power cells supplying the necessary thrust are extremely advanced by our own standards. I have removed a number of neural implants from the subject that appear to aid in the evasion of incoming projectile file. The engineering team has already suggested several ways in which this technology might benefit our soldiers.
