Default military binoculars in silent hunter

military binoculars in silent hunter

well there hasnt been one in any sh version, sh1 to sh4, i went no further than 4,
never had binoculars that in any way resemble those used by the military.

thats a real shame because military bino's are a precision instrument for measuring distances.
its way more precise than periscopes and TBT's.

it uses an angular measure called the mil, and 17.77 mils are in one degree.

a complete circle has 360 degrees, and in mils; 6400, so you can see how precise a mil is,
compared to the degree. this is the instrument used by an observer to call for and adjust indirect fire from the guns,
tankfire, cas, and naval gunfire.

but what do we have in sh? we have bino's that have a capability on the par of bird-watching.

below im posting a pic of a page from tech manual TM9-1611, dated 7/2/1942, it seems back then the navy used
a pair of bino's called the type EE, and its specs below the pic.










the difference between military and civilian bino's is that in military bino's, there a reticule in the eye piece,
that is used in calculating horizontal and vertical distances. the verticle scale measures vertical distance,
such as adjusting height of burst, and also to increase or decrease range, the horizontal scale measures a lateral shift in range,
and measures lateral distance, like the length of something, and then translating that length to a range, by whats called the
OT factor. (OT means observer to target)

ot of 1 == 1000 yds
ot of 2 == 2000 yds
ot of 3 == 3000 yds
etc....

an angle of one mil equates to one yard of lateral distance for every 1000 yards of range. Thus if R equals range in yards,
L equals lateral distance in yards, and M equals angular deviation in mils, then the following is true:
L = (R/1000) (M).





the reticule is set in the eyepiece so that its measure is 100 mils at 1000 yards.

the tick marks numbered from the point where the vertical and horizontal scales meet is zero mils, going out to left 5 and right to 5.
each tick mark is 10 mils, for a total of 100 mils at 1000 yds.

below i post a pic of the reticule of the M-19 binoculars, having something like this in our bino's would be a plus to the game,
adding to the realism, and a very fast way to determine lengths, ranges, and speed to, i dont see why not about speed.
