alternate in coaching each other. This method gives each man the necessary physical rest without halting the prog- ress of his instruction. He is learning while watching another man and attempting to correct his mistakes. (14) A great deal of preparatory practice is necessary in order to strengthen the muscles of the hand and arm and to fix the habit of correct trigger squeeze. The periods of exer- cise should not ordinarily be of long duration. Three or four 10-minute periods per day for a month will produce good results on the range. These periods of instruction can often be held during waits when troops are on maneuvers or field exercises. Some kind of a mark can always be found that will serve as an aiming point. (15) It is a good plan to have full-sized pistol targets placed in the vicinity of the barracks to encourage the men to spend part of their time in preparatory practice. (16) The preparatory exercises should be held out of doors with full-sized pistol targets, but during inclement weather they can be held indoors, using miniature targets, with good results. c. Scope of preparatory instruction.m(1) Each man’s pis- tol is closely examined for defects before the beginning of the preparatory instruction. (2) Every man who is to fire on the range should be put through the preparatory course. Part of the preparatory instruction may have escaped the men the previous year and part of it has certainly been forgotten: in any case it will be beneficial to go over it anew and refresh the mind on the subject. (3) In peace noncommissioned officers should be put through a rigid test before the period of preparatory in- struction for the organization begins This is also desirable in war when time is available. 46. FIRST STEP; Aiming.-a. Apparatus required–The ap- paratus required for a set of equipment is listed below. When an entire squad is engaged in this work there should be two sets of this equipment in order that a number of the men do not remain idle. The work of the squad can then be carried on as in rifle marksmanship.
