WARNING

•

White phosphorus (WP) impregnated felt wedges from the

M825/M825A1 are not totally consumed when the WP burns.

When the unburned felt wedges are crushed or moved,

residual WP will re-ignite, posing a burn hazard. Personnel

should not contact or move the unburned felt wedges.

•

The M825/M825A1 projectile is not to be fired if the obturator

is missing or broken because it may result in a short round. If

the band is displaced and can be repositioned and remain in

NOTE

•

The M825/M825A1 projectile consists of a modified M483A1

projectile carrier with a payload of white phosphorus

impregnated felt wedges. In-flight fuze functioning ejects a

canister.

A burster inside the canister scatters burning wedges over the

target area producing obscuring smoke.

•

The M825A1 projectile contains an improved payload and a

new base which have corrected the M825 projectile flight

instability. The restrictions imposed on the M825 projectile do

not apply to the M825A1 projectile.
