Orienting a 64-00 mils panoramic sight with the PAB-2M aiming circle
Orienting the panoramic telescope to mils 64-00 
1. The preliminary setup and orientation of the PAB-2M aiming circle is no different from the usual one. We end up with the aiming circle pointed in the main direction of fire (MDF) and the angle-measuring (red) scales zeroed.
Pay attention to the MDF. If you have chosen the MDF for the gun (in mils 64-00), you need to convert it into thousandths for the aiming circle. You can do this in Kropyva, or by dividing mils by 1.067 (the full number is 1.06666666667).
Example: MDF mils 15-00 / 1.067 = 14-06 thousandths.
So the MDF on the aiming circle will show 14-06 on the black scales, while the angle-measuring (red) scales are zeroed.
2. Lay the aiming circle on the gun's panoramic telescope and subtract the readings of the red scales from 30 if they are less than 30-00; if the readings are greater than 30-00, subtract them from 90.
3. Convert the obtained values back to mils 64-00 using Kropyva, or multiply by 1.067.
Then proceed as usual. Report the data after calculation to the gunner.
Example 1. Aiming circle angle 5-43.
30-00 — 5-43 = 24-57
24-57 × 1.067 = 26-22 to lay on the aiming circle
Example 2. Aiming circle angle 35-43
90-00 — 35-43 = 54-57
54-57 × 1.067 = 58-23 to lay on the aiming circle

Painting of 155 mm artillery projectiles
Ammunition components are painted primarily to prevent rust. Colors are used for camouflage, for recognizing the main use of the item and for identifying hazardous fillers used in the munitions. These are the colors used to indicate the main use of ammunition.
