Just sank a 19k ton escorted Euro Liner NW of PI. As we know, Sugar boats didn't have a TDC so I used the horizontal reticules on the objective lens of the scope.

In high power, each small mark = 15' MOA; each large mark = 1°.Top to bottom and side to side, lens face = 8°.
In Low power, each small mark = 1°; each large mark = 4°. Top to bottom and side to side, lens face = 32°.

Acquired first range and bearing, down scope...made plot, 3 min. later, acquired second range and bearing, down scope...made plot. Dist. travelled converted to 13 kn.

Computed OAC via ASIN (( 13 tgt speed / 31 torp speed ) x SIN 80 aob ) = 24°. Therefore, I fired a spread of 4 at the liner as she passed in front of 336° travelling left to right. All hit and she sank within 1 min. leaving 4 liferafts (RB-15's) braving the sea.

edit: btw, I might add that the escorts paid little attention to the proximity of the liferafts as they attempted to do me in. Interesting.
