_The Director_: “I think you have made a very good distribution of troops. I do not think you can say off hand that you would have the rifle grenadier always in the interior groups. His position must depend upon the prospective targets that he may have. Now, the distribution brings us down to the proposition of the preparation of four short sections of trench sufficient to shelter four men each. This makes it a comparatively simple proposition. You see, when you divide all of this work up in the way we have how it gradually clears up and becomes perfectly simple. “Let us now locate on the ground the four short sections of trench that will have to be prepared.” Procedure The class will now be conducted to the right of the section area and then along the front, and the exact location of the four short trenches will be determined upon. Each will then be traced on the ground so that the members of the class may see just the sector front that it may cover. If additional pits are required for the automatic riflemen they will also be indicated on the ground. One or more members of the class may be required to lie down on the ground and verify the field of fire from each trench. _The Director_: “Captain James, we have made a mark on the ground for each of these short trench lengths; we call that a trace; what do you mean by that?” _Captain James_: “That the line we have made is the upper edge of the interior slope of the parapet of the trench. It is the firing line of the trench.” _The Director_: “Now we have located these trenches; you have noted the distance apart they are. Would we try to connect them up with a continuous trench under the circumstances, Lieutenant Baker?” _Lieutenant Baker_: “No, sir. I think not. If any continuous trench is to be constructed it seems to me that it should be dug a few feet to the rear and parallel to our line of short trenches. Our short trenches can then be connected up with it by communication trenches running obliquely, to give cover from fire. I think this parallel trench should be traced now so that work can be commenced on it tonight after the fire trenches are completed. It should be a zigzag trench. The 3rd squad can get some work done on it before they have to go on outpost.” _The Director_: “I think we have covered everything that is necessary preliminary to issuing the order of the section commander except the location of the command post. Where would you locate it, Captain Hall?” _Captain Hall_: “I would locate it here (indicates). The questions of observation and communication are the determining factors in its selection.” _The Director_: “Now I want each member of the class to write out this order that Sergeant K would issue to his section guides. Make it simple and to the point.” The members of class will write out the order on their pads and when all have completed it the sheets are passed to the officer on the left for criticism.
