Excellence in gunnery is measured by hits per gun per minute; therefore, the primary end of gunnery training is the attainment of both accuracy and rapidity of gun-fire. Both of these features are essential; either is futile without the other.
Recently considerable attention appears to have been devoted to a study of the causes of inaccuracies in gun-fire, with a view of determining in what way development should tend in order to increase the percentage of hits at battle ranges. However, it is believed that the results of recent target practices indicate an urgent need, not only for an increase in percentage of hits, but also for the development of rapidity of gun-fire. This essential feature, to which so much attention is devoted on elementary practice, seems to receive inadequate attention when we come to long-range battle practice.
