Direct proof of use
FAS states that the M712 Copperhead was employed during Operation Desert Storm and that Copperhead projectiles destroyed Iraqi observation posts, border-guard posts, and forward radar installations during the first week of artillery attacks. The White Sands Missile Range Museum separately describes Copperhead use in Operation Desert Storm in 1991 against enemy artillery, radar, and observation positions.
Designation-Systems corroborates the conflict connection by listing operational U.S. Army use of the M712 Copperhead during Operation Desert Storm in 1990-1991. Together, the public sources support U.S. employment of the laser-guided projectile in the 1990 Gulf War, but they do not identify a public shot count, firing battery, or individual engagement record.

Timeline
Copperhead's documented Gulf War use falls within the 1991 Desert Storm combat phase. FAS places its attacks in the first week of artillery attacks, while White Sands identifies Operation Desert Storm in 1991 as the conflict in which the projectile was used against artillery, radar, and observation positions.
The accessible sources tie the round to Desert Storm use and broad target categories rather than a day-by-day fire mission chronology. The record therefore treats the January 1991 first-week reference as the most specific public timing claim and keeps later ground-campaign context separate from direct Copperhead use.

Battlefield role
Copperhead gave U.S. 155 mm artillery a precision option for point targets during Desert Storm. The projectile was guided in its terminal phase by reflected laser energy from an illuminated target, allowing cannon artillery to attack discrete positions such as observation posts, border posts, radar installations, artillery positions, and other hard targets rather than only area targets.
That role matched the weapon's design. White Sands describes Copperhead as a high-explosive, laser-guided anti-tank projectile fired from standard 155 mm howitzers, and FAS describes a cannon-launched, laser-guided projectile able to defeat armor and point targets. Designation-Systems adds that the M712 had a semi-active laser seeker, an anti-armor warhead, and a 3-16 km effective firing range.
