Analyst Note
This image shows a improvised rocket-assisted munition (IRAM). This particular munition consists of a 107 mm rocket motor with an industrial gas cylinder fitted in place of the standard warhead. The frost present on the cylinder indicates a pressurised gas was released. The yellow–green residue is consistent with a payload of chlorine gas. (ARES)

“Chlorine contained in a munition such as this is held under pressure; when the container is punctured – either by explosive means or impact alone – the liquefied chlorine vaporises. During this process, rapid cooling of the container occurs, causing adjacent humid air to form a frost on the container. This process, known as auto-refrigeration, indicates that the munition contained a pressurised gas payload.”
