Afganistan

I am willing to bet the creature that shot those two US Solders was one of Abbadons "Dead Thing Angels" not to be confused with locus. Abbadon and his angels have the ability to breach any passcode or password and are extremely stealthy. It is impossible to catch these creature unless he wants to get caught.

Dead thing creatures are reanimated cadavers I heard from a reliable source that one of these creatures was captured and when connected to an EEG machine they appear brain dead
Search "dead thing" on this site for more on these creatures
