As another example take the same general situation in such terrain that a glimpse is caught of the troop moving along a road but immediately it passes behind cover; several hundred yards beyond, if it continues on the road, the troop will again come into view and be exposed for a considerable stretch of road and within rifle range. What is done now? After the exercise the captain assembles the company and criticises the errors made and points out what should have been done. In the first situation opening fire by a few men would result in the hostile troop’s mounting and getting away with little damage or else in their getting their horses back under cover and being prepared to fight on foot. After the company once opens fire it will have a target but for a very short time; hence great care must be exercised in estimating the distance, dividing the target and giving the other necessary orders so as to produce the greatest effect in the least time. The captain should carefully study his problem and be prepared to give an instructive critique. [Sidenote: Suggestions for fire problems] A little book called “Fire Problems” by T. D. Pilcher of the British Army is recommended to our officers; it treats this subject more fully, gives several problems and shows how the solutions should be criticized. The problems must be gotten up, as a matter of course, to fit the ground you have. A great variety of fire problems is afforded by any terrain. There should be some problems in which more than one target is offered. In getting up problems do not let yourself be hampered by the critics who will tell you that a troop of cavalry would not have crossed your front without having discovered you or without having been warned by its patrols: you are teaching fire tactics, not cavalry tactics, and besides, even cavalry has been known to do foolish and careless things. Try to make the problem reasonable and one which might occur in war but do not discard a good fire problem which teaches a valuable lesson because the situation is one which ought never to arise in battle. Few problems that are tried out in maneuvers will ever be duplicated in that exact form in war but the tactical principles involved will recur often. [Sidenote: Distribution of fire problem]
