Analyst Note
In this image, part of the distinctive internal 'X-rib' arrangement is visible protruding from the base of an M825-series white phosphorus smoke projectile. This is a useful diagnostic feature that can be used to distinguish remnants of these munitions from those of similar projectiles (such as those using a hexachloroethane/zinc smoke composition) if markings are not visible (ARES)

“…M825-series projectiles can sometimes be distinguished physically after functioning, even if no markings are visible. Pieces of the M825 internal canister, such as the x-rib or the metal casing … may be found.”
