Appendix C Known Distance Firing

1. Purpose

Knows distance firing give» the rifleman an opportunity to apply all the principles learned during preparatory marksmanship training. It ia not a substitute for the standard rifle marksmanship program; ft has been added for use by those units that desire additional rifle trailing for their personnel. The rifleman learns to aero his rifle for all usable ranges and to make practical application of sight adjustments. It instills confidence in him and requires him to fire accurately in order to become an effective rifleman. Known distance firing consists of instruction firing on the 25-meter range and on the kpown distance range.

2. Organisation for Firing a. A known distance range moat be thoroughly organised to insure safe and efficient operation. A

suggested organisation for known distance instruction firing is shown in figure 158. It may be modified to fit local range facilities. A 70-point known distance range can adequately handle a company of 200 men organised into thrae orders with another unit furnithing pit details. If It is necessary for a company to furnish its own details» a range with 50 firing points is adequate with the company organised into four orders. The waiting period associated with four orders or less is used for the firers to rest and prepare for the next exercise. However, if it is necessary for a unit to use five or more orders, some type of concurrent training should be conducted to profitable utilise waiting periods.

6. The following personnel are recommended for efficient operation of the range: (1} One range officer.

(6) Two telephone operator« for each block of eight targets (one on the firing line and one in the pits».

(71 An ammunition detail as required.

(81 Three target operators per targets. (One operator per target can be used, but having an extra man per two targets will permit the operators to take breaks without interfering with the conduct of the firing J

c. The "A" target (FSN 6920-900-82041 is used for ranges from 100 to 300 meters, and the ,4B" target (FSN 6920-900-8205) is used for a range of 500 meters.

3» Conduct of Firing (General)

a. Commands for conduct of firing should be kept to a minimum and should be standardized. The proper commands are listed in the following paragraphs. In addition, preliminary commands to describe the particular exercise may be used.

b. The range officer should insure that his commands are relayed to the pit officer so that he can keep abreast of the firing being conducted. This may be done by public address system or by telephone. Before each firing exercise, the range officer should inform the pit officer what the next exercise will be, and give him any special instructions for target operation; for example, 'The next firing will be for zero. Mark targets after each shot," Or, for the slow fire, he may say, *'The next firing wilt be eight rounds, slow fire. Mark targets after each shot."

c. Telephone operators are used to relay commands to the pits as necessary and to pass on special instructions to target operators as requested by the assistant instructors. They should be informed that at no time are they to make known the identity of a firer on a particular firing point. The following commands are those normally required to be relayed to the pits:


(This indicates that the target has been fired upon, but has not been withdrawn for marking.)


(This indicates that the target has been withdrawn and a spotter placed in the hit, but the appropriate disk has not been used to show the value of the hit.)


(This indicates that the target was disked, but the value was not observed or understood by the firer.I

4. Firing Commands a. The following commands are general in nature and are to be altered where necessary.
