Fins Attached to Perforated Cylinder
Fins attached to a munition via a perforated cylinder. A fin assembly of this type is typical on mortar projectiles, and this expression is used for identifying these munitions rather than as a technical term.
OSMP713
Analyst Note:
This is an Iranian 60 mm mortar projectile, marked to indicate it is of the ‘high explosive, long-range’ type (“H.E L.R”). Both the munition body and fuze are marked to with the year of production (“2008”). Whilst the tan colouring is often indicative of Iranian-made munitions (especially where the fins are also painted), this is not diagnostic, and a combination of physical features and markings should be assessed to reach a positive identification.

OSMP260
Analyst Note:
As a result of the rapid introduction of new models and variants during ongoing conflicts, sometimes a munition is issued with a provisional designation, or with no designation at all. In other cases, the designation is not yet known to researchers. (ARES)
OSMP208
Analyst Note:
The OF-NMR is a rocket-assisted mortar projectile, which uses a solid-fuel rocket motor located in the cylindrical portion of the body, below the ogive, to extend its range. Rocket-assisted mortar projectiles are rarely encountered. (ARES)
OSMP216
Analyst Note:
The “+” marking is a weight classification symbol which indicates standard deviation. One “+” sign indicates a deviation from 0.33% to 1.00% of the stated weight. (ARES)
OSMP169
Analyst Note:
The 120 mm 3-Z-2 incendiary mortar projectile contains 6 incendiary elements, four large and two small. These are hollow steel ‘cups’ filled with an incendiary mixture of an unknown type, but understood to be comparable in effect to thermite. (ARES)
