Unnamed American Military Policeman

As an American military policeman (A.M.P.), this unnamed character in "Ad Astra" competes with Monaghan for control over the German prisoner. Mystified by the company of headstrong and independent aviators in which he finds himself, he insultingly asserts his authority over the French officer at the Cloche-Clos in Amiens, thus helping to bring on the riot. The French officer calls him a "devil-dog" - a World War I era slang term for a U.S. Marine (422).
