_The Director_: “Captain Howe, what do you think of telling the 1st section to use combined sights? Explain the use of combined sights.” _Captain Howe_: “The target undoubtedly calls for the use of combined sights. Whether it would be necessary for Lieutenant Y to direct the use of combined sights would depend on how well trained the section leader was. If I were at all doubtful I would order combined sights. “Combined sights is the method of engaging any required depth of ground by applying simultaneously overlapping zones of fire from two or more guns. The depth of the beaten zone is increased by ordering different elevations to be used by each gun. This type of fire is not necessary under 800 meters. When it is used, as many guns as possible should be employed with 100 meters difference if the error in range finding is probably great, and with 50 meters difference if the error is probably small. This kind of fire is used either to engage a target which is deeper than the effective beaten zone or against a small target when the range is not exactly known.” _The Director_: “Captain Burt, explain to the class how the section leader determines when the fire should be lifted.” _Captain Burt_: “The section leader is equipped with a type EE field glass which has an inverted sight leaf in the field of view. The glass is used as follows: “Align the inverted sight scale so that the announced range to the target will coincide with the target. “If the range to the target is 850 meters or less, note where the line in the graticule representing 1,350 meters cuts the landscape. “If the range to the target is 850 meters or over, add 500 meters to the range to the target, and locate the point on the landscape that is cut by this line. “If the point located on the landscape is at or above the feet of our own troops, it will be safe to fire. “The gunner in a similar manner determines when it is safe to fire by means of his rear sight so there is always a double check.” _The Director_: “Captain Smith, do you see any purpose in ordering a rate of fire of 200 for the first minute?” _Captain Smith_: “Yes, sir, it is important to place as great a volume of fire as possible on the enemy at the beginning of the attack. However, the guns cannot maintain such a rate for but a few minutes, so it is necessary to lower it. A rate of 125 to 150 could be maintained for 20 or 30 minutes, so it is safe to order that.” _The Director_: “Captain Jones, what do you mean by the ammunition point?” _Captain Jones_: “The machine gun platoon ammunition point consists of the transport corporal, one runner, and the four ammunition carts and four machine gun carts with their drivers. This ammunition point is responsible for maintaining the ammunition supply from the carts forward to the guns.”
