M69 incendiary M69 incendiary The M69 incendiary bomblet was used in air raids on Japan and China during World War II. They were nicknamed "Tokyo calling cards". The M69 was a plain steel pipe with a hexagonal cross section in diameter and long. It weighed about . The bomblet used napalm (jelled gasoline) as an incendiary filler, improving on earlier designs which used thermite or magnesium fillers that burned more intensely, but were less energy- and weight-efficient, and were easier to extinguish. In Germany they were filled with jellied oil and dropped in clusters of 36 in the non-aerodynamic M19 bomb. Over
Foam weapon Europe and the UK, the terms "latex weapon" and "LARP-safe weapon" are more common, and combat is usually referred to as "LARP combat". Non-latex foam weapons are primarily used in Jugger and in the Finnish LARP community. The primary concern in designing a foam weapon is safety; a pulled blow with a foam weapon should not hurt the target, and in systems that allow it, even a full-strength blow should not cause injury. Combatants who consistently fail to pull their blows are liable to be ejected from an event, or at least pulled out of the fighting for safety reasons.
