Incendiary weapons attempt to damage a target through combustive effects. While flammable chemicals and oxidizers are often utilized, laser and plasma weapons can be adapted as incendiary weapons as well. Modern structures are often nearly impervious to incendiary weapons, but the psychological impact of such weapons often finds favor among certain crowds. The most practical use of such a weapon is clearing out undesirable lifeforms from an area or installation. When trying to put out any possible fires caused by such weaponry, one must make sure to not use water in the case of a phosphorous fire, as the use of water to extinguish such fires only results in them becoming more active, requiring chemical extinguishers.
