Originally the training program consisted of six sections, each headed by a chief officer in charge of instruction in that area. These were Terrain Intelligence (headed by Raymond Grazier), Signal Intelligence (George Le Blanc), Staff Duties (Arthur Jorgenson), Counterintelligence (William C. Piper), Enemy Armies (Charles Warndof), and Aerial Photo Interpretation (Theodore Fuller). In very short order, three sections were added to the mix: Military Intelligence (Delbert Pryor), Close Combat (Rex Applegate), and Visual Demonstration (George Weber). The last section added to the mix was Enemy Order of Battle, drawing upon material gathered by British intelligence and published under the name Order of Battle of the German Army in October 1942. It was the task of the section chiefs both to serve as teachers at Ritchie and to supervise the instructors assigned to their particular section. They did this by observing classes and by holding weekly meetings to discuss and critique both the program and the instruction.

Some of the section chiefs, such as Austrian-born Charles Warndof and Oregonian Rex Applegate, held their positions throughout the war. Others, such as Theodore Fuller and George O. Weber, entered active service in Europe. For his service in Italy, Weber would receive the Silver Star, Purple Heart, and Bronze Star with Oak Leaf Cluster.

Because Britain was already far ahead of the United States in military intelligence training, British colonel Thomas Robbins came to Camp Ritchie in June to provide instructional oversight. Robbins had been stationed at the British School for Interrogators of Prisoners of War at Cambridge University, and he was an expert in all areas of intelligence instruction. Under his guidance, the Military Intelligence Training Center at Camp Ritchie, in the first few months, developed a full spectrum of specialty classes. The basic class instruction now consisted of ten curricular components.
