Sergeant B now does exactly as he would do in actual war. How does he signal to his patrol? Does he assemble his men? If so, how and where? Does he send a message back to camp; and if so, by whom, and is it written or verbal? (If written, Sergeant B actually writes it and delivers it to Private ----, with the necessary instructions. If verbal, it is actually given to Private ---- with instructions.) Captain A must in this case make notes of what the message was. In either case, Private ---- ceases to be a member of the patrol and joins Captain A as an observer. He should, however, at some later time be required to repeat his message to Captain A, on the assumption that he had reached camp with the same. The message, whether oral or written, should be thoroughly analyzed and discussed. Was it proper to send a message at this time? Does Sergeant B intend to remain in observation; if so, how long? (Captain A can give such information from time to time concerning the hostile patrol as Sergeant B might reasonably be supposed to learn in view of his dispositions. In order that Captain A may present natural assumptions, it is very essential that in his own mind he should, at the outset, assume a situation for the hostile forces and that he should consider himself as in command of all hostile troops. In this particular case he should assume himself to be in command of the hostile patrol, acting under certain specified orders similar to examples given, and he should conduct this patrol in his own mind in accordance with these orders, giving Sergeant B only such information as he might reasonably be expected to obtain in view of whatever action Sergeant B takes.) Will Sergeant B attempt to capture this patrol? If so, how? Will he avoid fighting and attempt to pass it unobserved; and if so, how and why? In this manner the exercise is continued. Care must be taken not to have the patrol leader or members state what they would do, but they must actually do it. Explanations and discussions may take place later. In a similar manner the director may inform Sergeant B (or any member of the patrol) that this hostile patrol is followed by a squad (on the assumption that it is the leading unit of an advance guard), and the exercise is then continued along these lines. The following are examples of assumption that might be made and carried out: (_a_) That the patrol is unexpectedly fired upon. (_b_) That one or more of the patrol is wounded. (_c_) That a prisoner is captured (let an observer act as prisoner). (_d_) That a friendly inhabitant gives certain information. (_e_) That a dust cloud is seen in the distance over the trees. (_f_) That a column of troops can be seen marching along a distant road. (_g_) That an abandoned camp is discovered and certain signs noted. (_h_) That the patrol is attacked by a superior force and compelled to scatter. There is practically no end to the number of reasonable assumptions that may be made.
