8 13. FUSE SETTING. Twelve trials; six with the bracket fuse setter, six with the hand fuse setter. Drill cartridges with fuses in good order set at safety are placed as in service. An officer of the battery commands, for example: 1. Corrector, 24. 2. 2700. At the last word of the command for the corrector, in trials with the bracket fuse setter, the candidate sets the fuse setter at the corrector, and, as the data are received, at the range ordered, receives the cartridge from an assistant, inserts its head in the instrument, sets the fuse and calls Ready. At the last word of the command for the corrector, in trials with the hand fuse setter, the candidate sets the fuse setter at the corrector, and, as the data are received at the range, ordered; with the aid of an assistant, sets the fuse, and calls Ready. No credits are given in the following cases: (1) If the fuse setter is incorrectly set for corrector or range. (2) If the candidate fails to obtain a correct fuse setting within one-fifth of a second. If the fuse setter is found to be correctly set and is properly operated, credits are given as follows: Time in seconds, exactly or less than... 8 9 10 11 12 13 14. DRILL OF THE GUN SQUAD. The candidate will be examined by questions and by requiring him to act as instructor of a gun squad. The subjects will embrace such parts of the following exercises (Drill Regulations for Field Artillery, 1911) as will thoroughly test the candidate's familiarity with the 9 service of the piece: Formation of the gun squad (par. 186); to form the gun squad (pars. 190 to 192); to tell off the gun squad (pars. 193 to 195); posts of the gun squad, carriages limbered (pars. 196 to 198); to post of the gun squad (par. 199); posts of the cannoneers, carriages limbered (par. 200); to post the cannoneers (par 201); to mount the cannoneers on the carriages limbered (pars. 202 to 204); to dismount the cannoneers from the carriages (par. 205, 206); posts of the cannoneers, carriages unlimbered (pars. 209, 210); preparation for action (pars. 220, 221); to load and lay (pars. 236, 237); to fire the piece (pars. 239, 241, 167); to change from direct to indirect laying (pars. 243, 154, 165); to shift the trail (par. 244); to change target (par. 245); to discontinue and resume the fire (pars. 246, 247); the manner of conducting the various methods of fire (pars. 250, 251, 253, 254, 257 to 259), but not including the giving of commands therefor. 15. MATÉRIEL. The examination of each candidate will be sufficiently extended to test his familiarity with the use and care of the matériel of his organization, and will be both theoretical and practical. The theoretical examination will be conducted by questions on the following subjects: Nomenclature of harness and of the parts and accessories of the wheeled matériel; use of oils; method of cleaning and lubricating parts and mechanisms; method of cleaning cylinder oil and of emptying and filling cylinders; use of tools; the kinds of projectiles, of fuses, and of powder actually issued for use, and their general purpose and effect, omitting questions as to construction, weight, manufacture, and technical description; the care and preservation of saddle and harness equipment in use; preparation of blank ammunition; precautions to be observed in firing blank ammunition; care and cleaning of cartridge cases. The practical examination will be conducted by requiring each candidate to adjust to an animal one or more parts of the harness; to perform or to direct the performance of one or more of the following operations: Breech mechanism, to dis12280-15 -2 10 mount, to assemble; elevating screws, to dismount, to assemble; hub liner, to remove, to assemble; brakes, piece and caisson, to adjust; wheel, to remove, to replace. The candidate will be given credits in each of the two parts of this subject based on half the total value allotted, but only the sum of the credits will appear in its report. FOR CANDIDATES FROM 2.95-INCH HOWITZER BATTERIES. 16. DIRECT LAYING. Twelve trials; six with the peep sight and six with the panoramic sight. The target will represent a shielded gun and caisson and will be placed, as nearly as practicable, at a distance of 1,000 yards from the gun used in the trials. The candidate kneeling at the left of the trail, an officer of the battery commands, for example: 1. Target, that gun. 2. Deflection, 10. 3. 2400. At the indication of the target, the candidate causes an assistant at the trail to point the piece in is general direcion; at the last word of the last command he sets off the deflection and the range ordered; corrects for difference of level of the wheels; operates the elevating apparatus; causes the assistant to move the trail so as to bring the line of sight upon the target; calls Ready, and steps clear. No credits will be given in the following cases: (1) If the sight is incorrectly set for deflection or range. (2) If, when the bubble of the cross level is accurately centered, the line of sight is found not to be on any portion of the target. If the piece is found to be correctly laid within the limits prescribed, credits will be given as follows: Time in seconds, exactly or less than 25 27 29 31 32 33 34 35 Credits.... 2.0 1.9 1.8 1.7 1.6 1.5 1.4 1.3 11 17. INDIRECT LAYING. Twelve trials. Two aiming points will be selected, one toward the front for two groups of three trials each, and the other toward the rear for two groups of three trials each. They should be of the types used in actual firing and, for the purpose of this examination, should be about 2 mils in width, well defined, of such height as readily to be brought within the field of view, and at least 1,500 yards distant. They should be clearly pointed out to the candidates. All of the howitzers of the battery will be placed in the order in battery and a candidate will be assigned to each, except to the right piece which will be the directing piece, For each group of three trials the board will assume a situation in the conduct of fire for adjustment by battery, commencing with the first salvo, that will require commands involving a shift of the trail for the first trial, and, for all trials, such deflection and deflection difference settings and changes of settings of scales, not exceeding the limits prescribed in paragraph 9 of this order, as may reasonably be expected in service. In trials with the aiming point in rear the candidate will be allowed an assistant who, from a position in front of the axle, signals to a man at the end of the trail to move it so as to bring the aiming point within the field of view of the sight. The candidates kneeling at the left of the trails, an officer of the battery commands, for example: 1. Aiming point, the chimney on that white house. 3. Open (Close) by 10. 4. Site, 295. 5. 2800. At the last word of the command for the deflection each candidate sets off the deflection, and, as the data are received, applies the correction for deflection difference appropriate for his piece; sets off the angle of site and range ordered; causes the trail to be shifted until the sight is directed upon the aiming point; corrects for difference of level of the wheels; oper 12 ates the elevating apparatus and causes the assistant to move the trail so as to bring the vertical hair on the aiming point; calls Ready, and steps clear. The trial being completed and the candidates again kneeling at the left of the trails, the officer commands, for example, in continuance of the assumed situation: 1. Add 120. 2. Open (Close) by 5. 3. 2400. At the last word of the command for the deflection, each candidate operates the sight and trail as before; causes the trail to be moved until the vertical hair is on the aiming point; calls Ready, and steps clear. The third trial is similarly conducted. The other groups of three trials are conducted in the same manner and at similar commands. No credits will be given in the following cases: (1) If the sight is incorrectly set for deflection, deflection difference, angle of site or range. (2) If, when the bubble of the cross level is accurately centered, the vertical hair is found not to be on the aiming point. (3) If there is an error of more than 50 yards in laying for range. If the piece is found to be correctly laid within the limits prescribed, credits will be given as follows: Time in seconds, exactly or less than... 28 30 32 33 34 35 3.5 3.3 3.0 2.8 2.6 2.3 Credits.. 18. FUSE SETTING. Nine trials. Drill cartridges, with fuses in good order set at safety, are placed as in service. The candidate, without touching the cartridge, places himself and holds the fuse setter in a convenient position. An officer of the battery commands, for example: 1. Corrector, 24. 2. 2700. |
