(Note.—The Director points out the limits of the front to be covered by the outguards.) “There are some definite rules that may be laid down governing the location of an outguard. In the first place, the location within reasonable limits has been designated by the support commander in his order. We are to cover the main road leading from the direction in which the enemy is reported to be. The outguard should occupy a good defensive position—that is, it should have a good field of fire to the front and in oblique directions toward both flanks. It should be so far concealed that the enemy could not discover it without attacking.” Procedure Situation No. 4 is now handed out to the members of the class. The Problem =Situation No. 4=: You, Corporal V, have been given the fifth squad, and ordered to establish outguard No. 2 in this vicinity. You have arrived at this point with your squad. _Required_: How will you carry out your mission? Procedure The Director reads the problem aloud and calls upon one or more members of the class to explain their understanding of it. _The Director_: “Now, I want each member of the class to visualize this situation—to consider himself as being Corporal V. You have arrived here with your squad to establish outguard No. 2. Just how do you propose to go about it? Captain Hastings, what would you do?” _Captain Hastings_: “Well, sir, I would first decide where I am going to post the outguard and then decide upon the number of sentinels I am to post and where I am to post them. I have the limits of the front assigned to me definitely pointed out. I must first find a location for the outguard that will cover this front.” _The Director_: “Have you decided upon such a location?” _Captain Hastings_: “Yes, sir. My outguard posted at —— would accomplish the desired results. In the first place, any considerable body of the enemy must travel at night on a well defined road or trail. He cannot strike off across country unless elaborate preparations are made for guiding his columns. We would know about any such preparations and could counter them. If I cover this main road and the country adjacent to it, I will be able to accomplish my mission.”
