Incendiary

Incendiary grenades produce intense heat by means of a chemical reaction. The body of modern incendiary grenades is often similar in appearance to that of a smoke grenade, though generally smaller in size. The filler can be various chemicals, and while white phosphorus is well known, red phosphorus is also used for a number of reasons, not least because it is more stable and requires ignition, making it a safer option for the troops using it. Incendiary grenades are usually used for various types of demolition and destruction of material.
