RANGE-FINDING INSTRUMENT
Each company is equipped with a range-finding instrument. All company
officers and sergeants should be proficient in using it. The accuracy of
this instrument will greatly depend upon the skill of the user, and the
visibility of the objective.
TRIAL SHOTS OR VOLLEYS
"If the ground is so dry and dusty that the fall of the bullets is
visible through a glass or with the naked eye, a method of determining
the distance is afforded by using a number of trial shots or volleys.
The method of using trial volleys is as follows: The sights are raised
for the estimated range and one volley is fired. If this appears to hit
but little short of the mark, an increase of elevation of 100 yards will
be used for the next volley. When the object is enclosed between two
volleys, a mean of the elevation will be adopted as the correct range.
The range may be obtained from a near-by battery or machine gun. This is
the best method when available."--Small Arms Firing Manual.
ESTIMATING DISTANCE TEST
This test is usually held after the record firing on the range has been
completed.
