By battle sight we mean the position of the rear sight with the leaf down, and it corresponds to a sight setting of 530 yards. The notch, H, that is used when the leaf is down is called the battle sight notch. The battle sight is the only one 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.
