_Lieutenant Ralston_: “In this case we agreed on the signal 3—4. When any of us approach the sentinel post of the outguard after dark we will use the recognition signal. If there is no danger of enemy patrols lurking in the vicinity the man approaching the post calls out 3—4; the sentinel on post answers the call by calling 3—4 and they both know that everything is all right and it is safe for the scout to proceed. If there is danger of enemy patrols discovering the signal should it be called out, the man coming in would approach the sentinel post cautiously. He would tap 3—4 on the stock of his rifle until it is recognized by the sentinel and the signal returned by the latter tapping 3—4 on the stock of his rifle.” (The method should be illustrated.) _The Director_: “Captain Harvey, why do we go to all this trouble?” _Captain Harvey_: “A sentinel on post, after he has been harassed by enemy scouts for a while, takes no chances. He generally shoots first and then challenges. The recognition signal is simply an expedient to lessen the chances of accident.” _The Director_: “Now all of these details may seem to be small affairs to you. But the man who knows them and requires them to be carried out in service is the man who will be successful in military operations. Almost any dub can blunder through, paying the price in the lives of his men. It is the man that knows all of the little details of tactics that will come through successfully with his command without the sacrifice of a man more than is necessary to accomplish his mission. The proposition of measuring accomplishment by the number of casualties is old stuff and will not go with the commander that is up to his job. It is the man who accomplishes his mission with the least number of casualties that is the successful military leader.” * * * * * =Reconnoitering Patrol= =Card No. 3= =Director’s Key= 1.
