At times, because of the tactical situation, the BC or gunner may have to estimate range. These methods are used only to estimate range.
• Flash to bang method
• 100 meter unit-of-measure method
29
100 Meter Unit Of Measure Method
100 M
200 M
300 M
4OO M
500 M
* The BC can accuratelydetermine range out to 500 meters using this method with practice.
29
Flash to Bang Method
Using this method, the BC determines the time it tookfrom the moment the flash was determined to the timethe Bang occurred. Then apply the following formula;
Second x 350 ( speed of sound ) = distance
Ex- 3 seconds from flash to bang observed by BC;
3 sec x 350 fps = 1050meters

FRONT AND FLANK TARGET VIEWS
*General Rule of Thumb;
If you see more of the front, it’s a frontal view, more of the flank, it’s a flank view.

5 MILS
6.75 METERS
Range determination using binoculars
The BMP is 6.75 meters long (W). Using binoculars, the BC determines that the BMP measures 5 mils in length.
Wm
= R
Substitute the two known values for W and mW
m= 6.75
51.35=
Since R is expressed in thousands of meters, multiply by 1,000; and round off to the nearest tenth, for example: .35 = .4; .31 = .30 1.40 x 1,000 = 1,400 meters, the range to the BMP.

AUXILIARY SIGHTTHE AUXILIARY SIGHT HAS A STADIA THAT ALLOWS BOTHRANGE ESTIMATION AND APPLICATION OF THE CORRECTSUPER ELEVATION BASED ON RANGE.
-THIS SYSTEM IS USED TO DETERMINE THE RANGEAND TO ENGAGE THE FRONTAL OR FLANK VIEWOF A TARGET.
-THE M792(HEI-T) SCALE GOES TO 3,200 METERS.
-THE M791(APDS-T) SCALE GOES TO 3,400 METERS.
-COAX FIRING IS CONDUCTED USING THE SAME METHOD
AS M792(HEI-T), USING THE M792 STADIA LINES.
