Direct proof of use
The White Sands Missile Range Museum states that Copperhead was used in Operation Iraqi Freedom in 2003, and identifies the target categories as enemy artillery, radar, and observation positions. Designation-Systems separately lists operational U.S. Army use of M712 Copperhead during Operation Iraqi Freedom in 2003, while a National Defense University technology paper also identifies the M712 as a laser-guided projectile used in Operation Iraqi Freedom.
The accessible sources support U.S. employment in the conflict and broad target categories. They do not provide a public shot count, named firing battery, or individual engagement chronology for 2003 Iraq War use.

Battlefield role
Copperhead was a cannon-launched guided projectile fired from compatible 155 mm howitzers and guided in its terminal phase onto reflected laser energy from a designated target. In the 2003 Iraq War context, the sourced role was precision fire support against point targets such as enemy artillery, radar, and observation positions rather than area bombardment.
The weapon's design explains that role: White Sands describes it as a high-explosive, laser-guided anti-tank projectile, and Designation-Systems notes its semi-active laser seeker, anti-armor warhead, and 3-16 km effective firing range. Those technical details support why it was suited to hard or discrete targets, but the conflict-specific claim rests on the sources that explicitly connect Copperhead to Operation Iraqi Freedom.
