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.
Analyst Note:
This Iranian 60 mm mortar projectile is of the ‘Long Range’ type described without a specific model name in various Iranian export catalogues and other sources. The designation as marked on projectiles and packaging is variable, with observed formulations including “60mm H.E. L.R.”, “60mm H.E L.R”, and “60mm HE L.R”. Sometimes, as here, “60mm L.R” is followed by “HE / TNT”. (ARES)
Analyst Note:
The M824 60 mm mortar projectile dispenses a parachute-retarded illumination flare which burns for 35 seconds. The tail portion of the munition (seen here) separates from the forward (body) portion and is sometimes found along the line of fire. (ARES)
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.

Analyst Note:
This Iranian M91 81 mm mortar projectile is marked to indicate it was produced in 2009. The AZ111A2 fuze fitted to the projectile is also marked with the same year of manufacture. (ARES)
Analyst Note:
This Iranian M48 120 mm mortar projectile is marked to indicate it was manufactured in 2008. A plastic bag cable-tied to the tail of the munition protects the auxiliary, or supplemental, propellant charges fitted to the round. (ARES)
Analyst Note:
The physical features, colour scheme, and packaging of these 120 mm mortar projectiles are all consistent with Iranian manufacture, but the markings are mostly obscured in this image. (ARES)
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)
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)
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)
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)
