M13 incendiary grenade

The M13 incendiary grenade is a Pyrosene-V- and white phosphorus-based anti-materiel and anti-personnel grenade in use with the United Nations Space Command Defence Force.

Design
The M13's body consists of a sheet steel cylinder, coloured olive drab with yellow band markings. The filler consists of a small explosive igniter and "scatter charge", and the main payload of Pyrosene-V, a fuel gel mix that can adhere to a target. Its effects are similar to that of napalm-treated gasoline, giving rise to the nickname "napalm grenade", but instead of the gasoline, polystyrene, and benzene mixture used in napalm, Pyrosene-V is a kerosene-based fuel with a lower concentration of benzene. It has has less impact on the environment than napalm, and also contains an oxidizing agent, making it more difficult to put out once ignited. Pyrosene-V burns at nearly 2,500 degrees Celsius and has a burn time of around sixty seconds.

The mixture also contains white phosphorus (WP), which burns fiercely and can set cloth, fuel, ammunition and other combustibles on fire. It cannot be doused with water and also releases toxic smoke. Incandescent particles of WP cast off by the initial explosion produce extensive, deep second- and third-degree burns. WP often stick to the skin, and phosphorus burns carry a greater risk of mortality than other forms of burns due to the absorption of phosphorus into the body through the burned area, resulting in liver, heart and kidney damage, and in some cases multiple organ failure. White phosphorus continues to burn unless deprived of oxygen or until it is completely consumed. The M13 can be affixed to targets through a combination of an adhesive base, or a magnetic pad.
