DURING THE DAY.
15.—Observation of open terrain.
When the terrain opposite is open country, the necessary observation may be done by the smallest possible number of men. Fire only, if any of the enemy are sighted. Then, have two rounds fired, then three. But keep fire under strict control. (If enemy continues to approach. Cf. [par. 52] ff.)
16.—Observation of covered terrain.
When the terrain is covered (high brush wood, copses, trees, etc.) a sharpshooter in each section should fire occasionally into the trees, etc., which may be observation or sharpshooters' posts but this should not be overdone.
