The M825A1 155 mm smoke projectile makes use of white phosphorus (WP) to generate a brilliant white smoke. Whilst WP does have incendiary effects, the method of dispersal in the case of the M825A1 is optimised for screening and marking purposes. (ARES)

“The M825A1 155 mm [white phosphorus; WP] projectile is designed to disperse a smokescreen by ejecting 116 felt wedges, each measuring 19 mm, impregnated with WP over the target location. These wedges ignite upon contact with the air and fall to the ground burning. This produces the tell-tale ‘snake-like’ trails of smoke associated with M825A1.”
