Charlie

The man who introduces himself as Charlie was an enlisted soldier under the command of the Flame Alchemist, Roy Mustang during the Ishval Civil War. When the long fighting finally ceased, Charlie brought it upon himself to speak to his distant commander and thank him for all the work he had done to keep all the men beneath him out of harm's way. He describes the column of flame that would precede their every march as a flame of trust that would inspire the infantrymen to push on without fear because they knew that their leader would not let them down. Seven years after the war, Charlie remains as a soldier in the East Area of Amestris, stationed under Lieutenant General Grumman. When it becomes apparent that his old commander is planning a coup d'etat in Central City in order to rid the government of corruption, Charlie and his friends are only too happy to return to the field. Charlie himself initiates the first attack of the coup by dynamiting the bridge on which King Bradley is traveling before heading off to Central to act as backup for the Colonel's main force. He leads the secondary team, eliminating the few Central soldiers who have managed to corner the Flame Alchemist while assuring his wounded enemies that soldiers from Fort Briggs wouldn't have bothered to leave them alive. Though devoted to the cause, Charlie reveals himself to be a staunch family man, accepting Mustang's offer to escape if the situation worsens so that he may return safely to his wife back east.
