One or more members of the class will be called upon to state his understanding of the situation and this will be continued until it is apparent that all members of the class understand it and are ready to proceed with a solution on the same basis of understanding. Explanation _The Director_: “Before going ahead with the problem I want to say a few words about the importance of this subject of approach march and deployment. “Prior to the war we did not appreciate the necessity for extensive drill and instruction in the subject of approach march, deployment and the relief of units on the firing line. There was little literature on the subjects and what there was dealt only in glittering generalities. Once in a while a training program included the subject ‘Deployment,’ but no one took it seriously and such as we carried out, were executed in a purely perfunctory manner.
