_The Director_: “I want to emphasize the necessity for this process of sizing up the situation on the part of all officers charged with a tactical operation. If you come to a decision without doing so you may be right and you may be wrong. The chances are greatly in favor of the latter. If you stop and consider the elements of the problem as outlined by Captain Hastings the chances are that you will be right. In any event you have the odds on your side. Lieutenant Wallace, what troops have been designated to support your company?” _Lieutenant Wallace_: “A part of the machine gun company and a howitzer platoon.” _The Director_: “You will note that these two units have been ordered to support your attack. They are not attached to your company. What do you understand to be the difference between a supporting unit and an attached unit?” _Lieutenant Wallace_: “An attached unit becomes an integral part of the force and is subject to its commander’s orders. A supporting unit receives its orders, not from the commander of the force being supported, but from another source, usually a common superior.” _The Director_: “That is right. I hope you all note the distinction. It is the rule, however, that the supporting unit must work with the unit that it is supporting in every way possible so as to insure teamwork in the accomplishment of the common mission.” “Lieutenant Ralston, how would you get your instructions to your platoon leaders, who are back with the company?” _Lieutenant Ralston_: “I have a runner with me from each of the three platoons. I would send these runners back to their respective platoons to tell the platoon commanders to report to me at ___________” (Lieutenant Ralston would indicate where the platoon commanders are to report.) _The Director_: “Let us assume that you are Captain C. Just what would you say to the runners?” _Lieutenant Ralston_: “I would call the platoon runners to me and say: “‘Do you see that ___________?’ (Designating a tree or other well defined object.) ‘Each platoon runner will deliver this message to his platoon leader—Platoon leaders will join Captain C at once at ___________ (Place). Repeat the message.’” _The Director_: “All right. Now let us assume that the platoon runners have started back to their platoons, what would you do now?” _Lieutenant Ralston_: “I would go over to the right to make a personal reconnaissance of the enemy strong point, select my line of departure for the attack and get the ‘line-up’ of the supporting weapons.” _The Director_: “That would seem to be the reasonable thing to do.” The Class is now conducted over to the right, to a point about the center of the line of departure for the attack.
