Its brain also appears to have an almost modular structure, able to rapidly section off disrupted brain structures.
The men are calling this beast the "Berserker." Although it shares the same structure as the Muton, for reasons yet unknown to us, the Berserker seems to be consumed by blood lust, with little regard for its own safety.
Although similar to the previously cataloged Muton species, this particular specimen is... different. Our troops have taken to calling this beast the "Berserker," based on its uncharacteristically aggressive tactics in the field. Despite sharing the same physiological structure of the other Mutons, for reasons yet unknown to us, the Berserker seems to be consumed by blood lust, charging into combat with little regard for its own safety. Current theories as to the cause of this behavior have led us to begin investigating possible genetic manipulation of the subject's endocrine glands, or, in the case, the equivalent glands that appear to secrete androgenic hormones. If the aliens enlarged or modified the action of these glands, it could explain the Berserker's outbursts. Specifics on this creature's abilities in combat should be available when using the Unit Analysis View on another specimen of the same type in the field.
