ESTIMATE RANGE

• AS AN ARMOR CREWMAN/CAVALRY SCOUT, YOU WOULD
  NORMALLY
• DEPEND ON THE LASER RANGE FINDER OF YOUR PRIMARY
  SIGHT TO DETERMINE THE
• RANGE TO A TARGET. HOWEVER, IN THE EVENT THAT
  YOUR VEHICLE'S RANGEFINDER
• OR PRIMARY SIGHT BECOMES INOPERATIVE, YOU MUST BE
  ABLE TO ESTIMATE RANGE IN ORDER TO CONTINUE TO
  ENGAGE AND DESTROY TARGETS."

Football-field Method.

• The length of a football field is 100 yards
  instead of meters, but it is a unit of measure
  most of you are familiar with. Estimate the
  number of football fields between you and the
  target for ranges up to 500 meters. Multiply the
  number of fields by 100 to determine the range in
  meters.
• (b)For ranges between 500 and 1000 meters, pick a
  point halfway between you and the target.
  Determine the number of football fields7,
  multiply by 100, then double the mount to find
  the range to the target.
• (c)In this example there are four to the halfway
  point, so multiply by 100 and double the amount
  and you will have the estimated range of 800
  meters.

Factors which may affect target appearance.

• Situations and conditions which may seem to make
  targets appear closer than they actually are
• a. Bright, clear day.
• b. Sun in front of the target. The sun is behind
  you or over your shoulder as you are looking at
  the target.
• c. High elevations. The target is at a higher
  elevation than you.

5
Factors which may affect target appearance.

• d. Bright colors (white, red, yellow). The
  target is brightly colored.
• h. Large targets.
• i. Desert.
• J. At sea

6
Factors which may affect target appearance.

• Situations and conditions which may seem to make
  targets appear further away than they actually
  are
• a.Fog, rain, hazy twilight.
• b. Sun behind the target.
• c. Lower elevations.
• d. Small targets.
• e.Dark colors.
• f.Camouflaged targets.

7
Recognition Method.

• Although the situations and conditions just
  discussed will also have some effect on the
  Recognition Method, the data on this viewgraph
  will generally hold true. You should be able to
  identify armored and wheeled vehicles from 1,500
  to 2,000 meters with the naked eye. If you can
  see the vehicle well enough to positively
  identify it as a tank but cannot determine the
  model, it is between 1,000 and 1,500 meters.

8
Flash-to-Bang method.

• In this method, range is determined by counting
  the seconds between the time that you see the
  flash and when you hear the sound of the gun
  firing. You can count the seconds by counting
  one-thousand-one, one-thousand-two, and etc.,
  with each count being one second. Since sound
  travels through the air at a speed of about 330
  meters per second, each second you counted equals
  330 meters.

9
Flash-to-Bang method.

• To determine the range to a firing weapon, watch
  for the flash of the weapon when it fires and
  start counting seconds immediately. The number
  of seconds you count, multiplied by 330, will
  give you the approximate range from the target to
  your position. If you must count higher than ten
  seconds start over at one. The same method is
  used during hours of darkness.

10
Binocular-reticle/mil-relation method

• For this method of range estimation you must know
  the mil measurement of the reticle in your
  binoculars and width, length, or height of the
  target, in meters, to figure range to the
  target.

11
Binocular-reticle/mil-relation method

• (a) Mil Values.
• (b) Known target size in meters. The average
  length of a threat tank is 6.7 meters and the
  average width is 3.4 meters.

12
Figuring the range.

• 1. Divide the known size of the target by the mil
  measurement from the reticle and multiply by
  1000.
• Example 6.7 divided by 3 X 1000 ? 3.4 divided
  by 2 X 1000 ?.
• 2. Remember that after you divide the size of the
  target by the mil measurement you must multiply
  your answer by 1000 to determine the correct
  range, in meters, to the target.
