How GBU-39 bombs became Israel’s ‘weapon of choice’

Analyst Note:
Whereas many cartridges are of the 'fixed' type—with the propellant charge contained entirely within the cartridge, and the cartridge case crimped around the projectile—the OF-540 artillery gun projectile is a type of 'semi-fixed' ammunition. A round of semi-fixed ammunition is separated into two groups of components: the projectile and fuze; and the cartridge case, primer, and one or more propellant charges. These two component groups are typically combined at the time of loading the gun, or shortly beforehand. The majority of ammunition fired by artillery systems is either semi-fixed or 'separate loading' (see Glossary). (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)
Analyst Note:
The AGM-88 High-Speed-Anti-Radiation-Missile (HARM) is an air-to-surface anti-radiation guided missile that seeks and destroys radar-based air-defence systems by detecting radar emissions, locking on to these, and using them to home in on a target. (ARES)
Analyst Note:
This image shows a 9M27K2 cargo rocket as well as several partially ejected PTM-1 anti-vehicle landmines. This 9M27K variant is fitted with the 9N128K2 payload section which carries and dispenses 24 PTM-1 mines. Other variants carry different mines or submunitions.
