Terrain Exercises — Inside the Classic

The Director as Author and Arbiter

The manual assigns the Director an outsized role. The introduction states that success depends almost entirely on the Director’s ability, tactical knowledge, and personal preparation. In the excerpts, the Director does not merely facilitate—he judges. When Lieutenant Ralston argues that flank patrols are unnecessary, the Director responds with a pointed explanation: “Never send out a flank patrol unless there is some sound tactical reason for it.” The Director then collects sketches, redistributes them to different students, and invites criticism. This structure makes the Director the sole authority on tactical correctness, turning each exercise into a demonstration of his own doctrine rather than an open exploration of alternatives.

Scripted Problems, Not Free Play

Each exercise follows a rigid sequence. The Director hands out a printed situation slip, reads it aloud, and then explains why the class is at that exact location. For example, Advance Guard Card No. 3 instructs the Director to “conduct the class to the place where the situation is to be taken up” and then “explain why Situation is taken up at this point instead of five miles farther on.” The problem is not discovered in the field; it is staged. The students’ task is to respond to a predetermined scenario—enemy movement, terrain features, unit dispositions—and produce a sketch or verbal solution. The manual’s table of contents lists nine exercises, each with a specific tactical focus (attack of a strong point, approach march, defensive position, etc.), reinforcing that the book is a curriculum, not a simulation engine.

The Gap Between Subject and Practice

The catalog subject for this record is “Tactics,” and the manual indeed teaches tactical principles. But the excerpts reveal that the book’s primary content is not tactical theory but classroom management. The introduction defines terrain exercises as “the logical step in tactical training, between the theory and practice of the classroom and the practical training with troops.” Yet the text itself is a guide for running those exercises—it tells the Director when to hand out cards, how long to allow for sketches (10–15 minutes), and how to collect and redistribute them. The actual tactical content is embedded in the situations and Director’s keys, which are only partially reproduced in the excerpts. A reader expecting a treatise on tactics will instead find a manual for conducting a specific training method.

Terrain Exercises is best approached as a period artifact of U.S. Army interwar training doctrine. Its value lies not in the tactical solutions it prescribes—many of which are now dated—but in the pedagogical structure it codifies. Readers interested in the history of military education will find a clear example of how the army sought to standardize tactical thinking through scripted field problems. Those seeking combat narratives or modern doctrine should look elsewhere.

There’s something humbling in that 1923 manual’s quiet assumption that ground itself teaches, if you’ll only look. It reminds me of another old friend, the way The war myth in United States history — A Closer Reading lingers on what we choose to see in a landscape of memory. Both feel like conversations left half-open, waiting for a patient reader’s return.
