TM 9--2350--311--10 Change 4 5--17 Table 5--1. 155MM AMMUNITION FOR M109 HOWITZERS — CONTINUED Authorized Projectiles Remarks Fuzes Identification Classification M825, M825A1 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 the groove, the projectile can be fired. 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. Smoke (WP) M825 : Light green w/ 1/yellow band M577 series MTSQ, M762 series ET For producing screening smoke Red marking M825A1 : Similar to M825 and a red band near top of projectile.
