point. Now your first reading on the image will be the mils from point A to B with point A on the far left part of the image
(see Fig. 3). Your second reading will be from point C to point B where point B is now the spot on the image where point
B ended after the first reading. After calculating the mils for each image, you then can add them together to get the total
azimuth reading. In the (Fig. 3) image below, the ship is longer than the total 100 mils available on the reticle. However, by
doing the foregoing mil calculations, you can now obtain the ship's total mil azimuth of 130 mils ( 60 + 70 ).

Upper and lower angle measurement:
Upper and lower angle means the angle included between any two targets (or two ends of a target) against the vertical line on
the reticle.
An upper and lower angle measurement is similar to measuring the azimuth. When the upper and lower angle measurement is
very small, aim the cross center of reticle at lower part of the target, read the scale value at the top of the target. The value is the
measured mils of angle included between the upper and lower parts. As shown in Fig. 4, the value of the lower part is 40, the
angle included between the upper and lower parts of the target is: (28075) 0-75 (75mils) / (280750) 0-60 (60 mils).
