Painting of 155 mm Artillery Projectiles
Color by primaryuse
Ammunition components are painted primarily to prevent rust. Colors are used for camouflage, to identify the primary use of an item and to identify hazardous fillers used in ammunition. These are the colors used to indicate the primary use of ammunition.
Markings on projectiles:
• Yellow - High-explosive fragmentation
• Brown - Reduced explosive effect
• Gray - Chemical
• Light green - Smoke
• Light red - Incendiary
• White - Illuminating/pyrotechnic
• Black - Armor-piercing
• Aluminum (silver) - Countermeasure.
• Blue - Practice
The most commonly used color for painting projectiles is dark olive drab. It is used only for camouflage and has no meaning. Markings on the projectile, such as those in yellow, indicate that it is a high-explosive fragmentation projectile.
Color bands on projectiles.
Bands are usually used to identify the types of components in the ammunition. In some cases, however, the color of the band indicates the primary use.
Band colors and their meanings:
• Yellow. High-explosive fragmentation effect (HE). The explosive filler is used to burst the casing and, for example, to disperse smoke mixture or toxic chemical agents, or to scatter anti-personnel mines.
• Brown. Contains a low-explosive charge. Low-explosive charges are usually used for registration fire or to expel the payload from the projectile.
• Dark green. Contains a toxic chemical agent.
• Dark red. Contains a riot-control chemical agent.
• Violet. Contains an incapacitating chemical agent.
• White. Indicates an illuminating munition.
• Black. On a high-explosive fragmentation projectile, this means an armor-defeating capability.
Combining color codes
On some types of ammunition, several color codes can be used on one projectile
to identify the primary use, component types and hazardous materials. (See the figure) Example:
1. Base color. Light green means the primary use is smoke.
2. A yellow band means the item contains a high-explosive charge.
3. Markings. Light red markings mean the item also has an incendiary effect.

Now, if you combine your knowledge of color codes with what you have learned about markings, you can fully identify this item. It is a 155 mm howitzer smoke projectile filled with white phosphorus (WP), with a high-explosive fragmentation bursting charge.

LOT – batch identification number. How to read it

DODIC - US Department of Defense identification code
Orienting a 64-00 mils panoramic sight with the PAB-2M aiming circle
1. Setting up the PAB-2M and orienting it is no different from the usual procedure. We finish with the aiming circle "looking" at the base direction of fire (BD), and the red scales zeroed.
Pay attention to the BD. If you have chosen the BD for the gun (in 64-00 mils), you need to convert it to thousandths for the aiming circle. This can be done in Kropyva or by dividing the mils by 1.067 (exactly 1.06666666667).
Example: BD 15-00 mils / 1.067 = 14-06 thousandths.
So the BD on the aiming circle will read 14-06 on the black scales, with the red ones zeroed.
3. We point the aiming circle at the panoramic sight and subtract the red-scale readings from 30 if they are less than 30-00; if the readings are greater than 30-00, we subtract them from 90.
3. We convert the resulting values back to mils using Kropyva, or multiply by 1.067.
Then everything proceeds as usual. We report the data to the gunner after the calculation.
Example 1. Aiming circle reading 5-43.
30-00 — 5-43 = 24-57
24-57 × 1.067 = 26-22 set on the aiming circle
Example 2. Aiming circle reading 35-43
90-00 — 35-43 = 54-57
54-57 × 1.067 = 58-23 set on the aiming circle
