TF 2-2 IN FSE AAR: Indirect Fires in the Battle of Fallujah.出典Fallijah WP

9. Munitions.

The munitions we brought to this fight were 155-mmhighexplosive (HE) M107 (short-range) and M795 (long-range) rounds, illumination and white phosphorous (WP, M110 and M825),with point-detonating (PD), delay, time and variable-time (VT) fuzes. For the 120-mm mortars, we had HE, illumination and WP with PD, delay and proximity fuzes . We also carried 81-mm HE with the same fuzes.

b. White Phosphorous.

WP proved to be an effective and versatile munition. We used it for screening missions at two breeches and, later in the fight, as a potent psychological weapon against the insurgents in trench lines and spider holes when we could not get effects on them with HE. We fired “shake and bake” missions at the insurgents, using WP to flush them out and HE to take them out.

c. Hexachloroethane Zinc (HC) Smoke and Precision-Guided Munitions.

We could have used these munitions. We used improved WP for screening missions when HC smoke would have been more effective and saved our WP for lethal missions.

We had several important targets, often reinforced houses that FOs had eyes on, that would have been more effectively engaged with a precision-guided munition, such as Copperhead with its shaped charge or the developmental Excalibur Unitary round that is concrete piercing (to be fielded in 2006). Barring the use of such precision-guided munitions, concrete-piercing (CP) fuzes would have been more effective than delay and PD fuzes were, but the latter were satisfactory.

(1) Hexachloroethane. Hexachloroethane (HC) smoke (smk) projectiles are available for 105-mm and 155-mm howitzers. They are used for screening, obscuration, spotting, and signaling purposes. The projectile has no casualty-producing effects. This base-ejection projectile is ballistically simailar to the HE projectile. It is fitted with a mechanical time fuze M565 or M577. The round expels smoke canisters that emit smoke for a period of 40 to 90 seconds.

(2) Burster-type white phosphorus. White phosphorus projectiles are available for 105-mm and 155-mm howitzers. They are bursting-tube type projectiles that can be fired with point-detonating (PD) or MTSQ fuzes. The projectile has an incendiary-producing effect and is ballistically similar to the HE projectile. Normally, shell WP is employed for its incendiary effect. The projectile also can be used for screening, spotting, and signaling purposes.

(3) M825 white phosphorus. The M825 WP projectile is an FA-delivered 155-mm base-ejection projectile designed to produce a smoke screen on the ground for a duration of 5 to 15 minutes. It consists of two major components--the projectile carrier and the payload. The projectile carrier delivers the payload to the target. The payload consists of 116 WP-saturated felt wedges. The smoke screen is produced when a predetermined fuze action causes ejection of the payload from the projectile. After ejection, the WP-saturated felt wedges in the payload fall to the ground in an elliptical pattern. Each wedge then becomes a point or source of smoke. The M825 is ballistically similar to the M483A1 (DPICM) family of projectiles.
