2 Analyst Notes:
This image shows 122 mm high explosive (HE) artillery gun projectiles manufactured in three different states, L–R: Iran, North Korea, and Russia. Whilst these examples are distinct from one another—particularly in coloration, as well as the presence or absence of paint over the driving band and bourrelet—this is not always the case, and a combination of physical features and markings should be assessed before identification is made.

Use the detonation of an explosive to propel small fragments of material from the body of the munition at high velocity
