Definition. "A military map is a drawing made to represent some section of the country, showing the features that are of military importance, such as roads, bridges, streams, houses, and hills. The map must be so drawn that you can tell the distance between any two points, the heights of the hills, and the relative positions of everything shown." (Field Service Regulations.) In the field the military maps are supplemented by sketches, or field maps, prepared from day to day. For facility in reading, military maps are made according to a uniform system of scales and contour intervals as follows: Road Sketches. Three inches on the map is equal to 1 mile on the ground, contour intervals of 20 feet. Position and Outpost Sketches. Six inches on the map arc equal to 1 mile on the ground, contour intervals of 10 feet. Manœuver or War Game Maps. Twelve inches on the map are equal to 1 mile on the ground, contour intervals of 5 feet. Large Strategical maps for Extended Manœuvers. One inch on the map is equal to 1 mile on the ground, contour intervals of 60 feet. Every officer in the Reserve Corps should be able to read a military map and make a road, an outpost, and a position sketch. BAYONET Importance of the Bayonet. The infantry soldier is armed with a bayonet. He relies mainly on fire action to disable the enemy, but he should know that it is often necessary for him to cross bayonets with the enemy. Therefore he must be instructed in the use of the rifle and the bayonet in hand-to-hand encounters. The present European War is demonstrating the importance of this instruction. If you did not receive instruction in bayonet fighting at a federal training camp, it was not because it is unimportant, but because there was no available time to give it. Any Reserve Officer can well afford to specialize in this work. AMMUNITION An infantry soldier goes into battle carrying 220 rounds of rifle ammunition. He habitually carries in his belt 100 rounds and when a fight is imminent he gets 120 rounds (2 bandoliers) from his combat train. He keeps 30 rounds in the right pocket section of his belt to be expended only when ordered by an officer. A cavalryman goes into battle carrying 150 rounds of rifle ammunition and 40 rounds of pistol ammunition. He habitually carries in his belt 90 rounds of rifle and 20 rounds of pistol ammunition. When about to go into a fight he gets 60 rounds of rifle and 20 rounds of pistol ammunition from his combat train. All officers must train their men to economize in the use of ammunition. Train service, even by rail for ammunition, would be inadequate if this were not done. TRANSPORTATION
