The battle sight is the only sight used in rapid fire. In unexpected, close encounters the side that first opens a rapid and accurate fire has a great advantage over the other. Again, a soldier on patrol generally has no time to set his sight, if suddenly attacked at close range. The battle sight, may, therefore be called the emergency sight,—the handy, quick sight. The soldier should, therefore, become thoroughly familiar with the use of this sight.

Battle sight
The sighting notch in the slide with the rear sight leaf down, is the same height as is the sighting in the drift slide when the rear sight leaf is raised and set at 530 yards.
That is to say, battle sight is equivalent to a sight setting of 530 yards. Therefore, in shooting with battle sight at objects nearer than 530 yards you must aim lower.
Kinds of Sight
[1353]. (Amount of front sight taken)
(a) Normal sight. The amount of front sight taken in [Figs. 6] and [8], is called the normal sight and is the one that the soldier should always use, either with the open notch or peep sight, as it is the only sight which assures the taking of the same amount of front sight every time. In other words it assumes a greater degree of uniformity in sighting, which is one of the most important factors in shooting. By uniformity in sighting is meant taking the same amount of sight each time.
If you take less than the amount of front sight used in the normal sight, it will, of course, have the effect of lowering the muzzle of the piece, and consequently you will hit a point lower than if you had used the normal sight.
On the other hand, if you take more than the amount of front sight used in the normal sight, it will, of course, have the effect of raising the muzzle and consequently you will hit a point higher than if you had used the normal sight.
