“No further information of the enemy. Corporal Jenkins’ squad has taken up a position on the road leading to the flank about —— yards from the cross-road. “You will take up a position on the road on which the flank guard is marching covering the cross-road. “Messages to cross-road.” _Required_: What action do you, Corporal Vincent, take? Procedure _The Director_: “Now, I want each member of the class to consider himself as being Corporal Vincent. You have just arrived here with your squad and received the order of Sergeant Wilkins. It is up to you to select the point where you are going to place your squad to cover the road. I want each of you to solve this phase of the problem independently. Make a rough sketch showing the position, and write out the orders that you will issue as squad commander. Twenty minutes will be allowed for the purpose. It is now —— (state time).” At the end of twenty minutes the class is assembled. The solutions are collected and redistributed. One or more members are called upon to read the solution he has in his possession. The position will then be selected and the Director will give a statement of the orders that would be issued. This may have been previously prepared for distribution to the class as “a solution.” The solution of each member of the class is returned to him in order that he may compare it with the solution submitted by the Director. Explanation _The Director_: “This is the termination of this Terrain Exercise. Let us see what we have gotten out of it—of what tactical benefit it has been to us. “The first situation was devised to show you the tactical necessity for a flank guard, the duties that devolve upon it, and the formation that is best calculated to enable it to carry out its functions. “The second situation was devised for the purpose of illustrating the necessity for covering approaches by which an enemy may cut in on the main body of a column and delay or annoy it. Further, the method employed in giving orders and instructions while continuing to march. “The third situation was devised to give you experience in giving orders to and conducting a combat patrol along the road. “The fourth situation brings out the elements contained in a tactical ‘estimate of the situation’ and the selection and occupation of a small position. “The fifth situation was devised to give you practical instruction in the methods of troop leading; rendering a quick decision on the appearance of the enemy and handling a squad in action. Also in making an estimate of the situation and rendering a decision when your mission has been carried out and circumstances which could not have been foreseen have arisen and it is necessary to embark on a new mission on your own initiative and without orders—in other words, when a man is thrown upon his own resources and has to decide for himself what he is going to do.
