Subtension refers to the length between two points on a target, and is usually given in either centimeters, millimeters or inches. Since an mrad is an angular measurement, the subtension covered by a given angle (angular distance or angular diameter) increases with viewing distance to the target. For instance the same angle of 0.1 mrad will ...
Some Leupold hunting sights with duplex reticles allow range estimation to a White-tailed deer buck by adjusting magnification until the area between the backbone and the brisket fits between the crosshairs and the top thick post of the reticle. Once that is done, the range be read from the scale printed on the magnification adjustment ring.
Conversely, the arc, line segment or curve section confined within the rays of an angle is regarded as the corresponding subtension of that angle. It is also sometimes said that an arc is intercepted or enclosed by that angle.
The most common reticles used today in red dot sights both for handguns and rifles are small dots covering between 0.6 and 1.6 mrad (2 to 5 MOA). The choice of red dot reticle size depends on the user needs.
A reticle with markings (hashes or dots) spaced with a one mrad apart (or a fraction of a mrad) are collectively called a mrad reticle. If the markings are round they are called mil-dots . In the table below conversions from mrad to metric values are exact (e.g. 0.1 mrad equals exactly 10 mm at 100 metres), while conversions of minutes of arc ...
How much of the US is in a drought? Overall, 38.9% of the contiguous U.S. is in drought, which is down about 13% since early November, according to the most recent U.S. Drought Monitor, out ...

Soldier observed at 400 m: The stadiametric rangefinder in the bottom-left corner of the PSO-1 telescopic sight reticle can be used to determine the distance from a 1.70-meter (5 ft 7 in) tall person or object from 200 m (bracket number 2 to the right) to 1,000 m (bracket number 10 to the left).
