 In the following table, the number of hits per 100 rounds fired, at a target 1 m. high, by the marksmen named, is shown under—

"a" When the fire is controlled and the appropriate elevation is used;

"b" When each skirmisher has selected the elevation corresponding to his estimate of the range. In this case it is presumed, however, that the ranges are generally estimated correctly. (, Schieszlehre für die Infanterie, 2nd Edition, p. 102).

The above table shows that when the elevation selected is in error, the number of hits decreases more rapidly the greater the skill of the marksman; and that an error in estimation is of less importance than marksmanship only at ranges under 800 m.
