Lieutenant John Macklin works in Intelligence for Banning. He is the officer in charge of the convoys from Shanghai to Peking. Macklin writes a report blaming McCoy for the problems on the convoy, not knowing Sessions wrote a report based on the truth. Called home from China, he is assigned as a mess officer at Quantico, where he causes problems for McCoy at the Platoon Leader's Course at Quantico and almost has him kicked out, when Captain Jack Stecker intervenes.
