A sergeant armed with a trapdoor
The man on the left firing his Army Colt is intended for use as a sergeant, he is wearing his sack coat which is quite handy to facilitate the painting on of chevrons - I haven't sculpted these on, as I don't really like to find sculpted-on chevrons when I'm painting, but without them, we have the choice of varying his rank to first sergeant, corporal etc. The next figure is an officer in sack coat and wearing a civilian hat, he holds an Army Colt revolver. The bugler rests his bugle on his hip, and in his left hand holds a Schofield Smith & Wesson revolver which he has acquired despite this classy revolver being bested by the Colt in trials for general issue, as the Colt could chamber S&W rounds, but the S&W would not take Colt ammunition. The officer on the right has a Springfield Officers' Model rifle, which, as one might expect, is a better specification version of the models issued to the enlisted men; among other things it featured chequering on the stock, a cleaning rod stowed beneath the barrel and a detachable semi-pistol grip addition behind the trigger guard.
