The nominal diameter of a projectile. For most modern munitions, this is expressed in millimetres (e.g. 82 mm mortar projectile), but older artillery gun projectiles may be described in inches.
The M825A1 155 mm smoke projectile makes use of white phosphorus (WP) to generate a brilliant white smoke. Whilst WP does have incendiary effects, the method of dispersal in the case of the M825A1 is optimised for screening and marking purposes. (ARES)
This image depicts either a 9M27K or 9M27K1 cargo rocket (cluster munition). The 9M27K carries the 9N210 high explosive fragmentation (HE-FRAG) submunition, whilst the 9M27K1 carries the 9N235 HE-FRAG submunition (ARES).
Contextual information suggests that this is likely a 9M22S unguided incendiary rocket (see External Research section), but this cannot be confirmed on the basis of this image alone. (ARES)
Some artillery projectiles, such as this M150 type, use a hexachloroethane-based composition (HC) to generate smoke for screening or marking purposes. In many armed forces, HC smoke munitions have partially replaced those relying on white phosphorus for similar effects. (ARES)
107mm spin-stabilized rockets of this design are often utilized by non-state actors in an indirect fire role. Like the original Chinese models that they are copied from, they do not require more than a simple electric power source and a rudimentary launch platform to achieve an acceptable level of accuracy.

Once fired, four canards will deploy from the forward (ogival) section of these M982 Excalibur guided artillery projectiles. The narrow-shaped ports through which the canards deploy are a good indicator of a guided or extended-range artillery projectile. (ARES)
Many guided (or otherwise complex) munitions like this one are marked with additional information on individual assemblies or components. This can include information on sub-contractors that produced or integrated specific parts of a munition. (ARES)
In this image, a Ukrainian soldier is using an M1155 Enhanced Portable Inductive Artillery Fuze Setter (EPIAFS) to input the target coordinates and set functioning parameters for an M982 Excalibur guided artillery projectile. (ARES)
The image is of "a high-velocity shell fired from the main armament of a battle tank," Desmond Travers, former director of the Institute for International Criminal Investigations, told Airwars and AFP. "The calibre appears to be 120 mm, and the shell is fin-stabilised. The maximum effective range is five kilometers, but a skilled tank crew member should be able to hit a target the size of a car." (Airwars)
Cargo rockets often use an internal frame to manage the correct carriage and expulsion of submunitions. These internal frames frequently survive largely intact after the munition has functioned, and may be diagnostic in identifying a munition by type, series, or model. (ARES)
The large fragments in this image are typical of 'natural' fragmentation resulting from the rupturing of a thick-walled munition (in this case, an artillery projectile) by the functioning of its explosive payload. (ARES)
The munition remnants pictured here are likely to be from either a Russian OG-9 or a Bulgarian RHEF-9MA/GHEF-9MA recoilless gun projectile. However, based on the available information, positive identification cannot be not be made. (ARES)
Like the more common 9M22S rocket, the 9M28S carries the 9N510 warhead, which dispenses 180 individual incendiary elements composed of a magnesium alloy shell filled with a thermite-like incendiary composition. (ARES)
