Batteries A, B, and E, along with the 507th Maintenance Company and HHB, 5-52d ADA, were assigned to 31st Air Defense Artillery Brigade, under Colonel Heidi Brown, the first female Patriot brigade commander, to provide air defense coverage for Coalition forces entering Iraq.

Alpha, Bravo, Echo, and HHB batteries were provided security (prior to and during the invasion) by the Companies A and C of the 3d Battalion, 124th Infantry Regiment (Florida Army National Guard) from Kuwait to Baghdad.

During the invasion, Battery E was bombed by friendly aircraft outside of FARP shell, which created a 30-by-30-foot hole and damaged the radar system.

The mistake was due to lack of rest, limited communications and human error according to a United States Army investigation.

Prior to invasion, 5-52d ADA had never conducted a bounding movement exercise to the extent Operation Iraqi Freedom required.
