3. The location and importance of dominating points in either line.
4. The importance of being able to pick out on the ground any points of special importance or danger indicated on sketches or maps turned over to him, and to determine from maps drawn to scale the ranges to such points.
5. How to find his way by the aid of a map or sketch from his post to any specified point in our own trenches, and back again.
6. The importance of being able to intelligibly record and graphically represent matters of importance to his commanding officer or to the sniper who is to relieve him. In this connection the special importance of exact truth in statements of fact, and of the careful separation of matters of fact from those of mere report or conjecture, should be duly stressed. Hearsay and conjecture are often of great importance, but should be transmitted as such, and in the case of conjecture the reasons therefor should be stated.
The above are simply a few instances to suggest to the instructor how to go about the matter of instruction. Many men will be already familiar with the subject, and the method may be abridged, but in the case of an entirely uninstructed man a step-by-step method of instruction must be followed. The training should be such that it will be an entirely natural matter for the sniper to observe and report as to:
1. The attitude of the enemy (whether aggressive, alert, active, etc.).
2. Description of enemy seen, uniform, arms, etc.
3. Any new work evident; such as trenches and obstacles strengthened, new emplacements, etc.
4. Position of machine guns, observation posts, sniper posts, etc., discovered.
5. Points in our own lines found to be specially dangerous, and points of enemy line that menace them.
