Colonel Ernesto Rabina Air Base (Crow Valley Gunnery Range)

Colonel Ernesto Rabina Air Base (CERAB), also known as Crow Valley Gunnery Range and formerly designated as the Tarlac Military Testing Ground, is a military reservation and bombing range located at Camp O'Donnell in Tarlac, Philippines, 22 kilometers from Clark Air Base.

Originally a component facility of Clark Air Base during the United States military presence in the Philippines, the site was used by the US 13th Air Force. During the 1980s, range security was assigned to the 3rd Tactical Electronic Warfare Training Squadron, while the attached 6009th Security Police Training Squadron conducted air base ground defense training. The Air Force Office of Special Investigations conducted counterintelligence training at the location, supported by Operating Location Delta of the 1961st Communications Group.

Prior to 1991, the 17,814-hectare facility contained an airfield, radar installations, electronic warfare equipment, and a surface-to-air missile site. These structures were buried by pyroclastic flows and lahar during the 1991 Mount Pinatubo eruption. Presidential Proclamation No. 163 in 1993 reserved the area for the Department of National Defense and the Armed Forces of the Philippines. The Philippine Air Force assumed control of the range in 2002 and officially renamed the installation Colonel Ernesto Rabina Air Base on September 28, 2016.

The base is operated by the Armed Forces of the Philippines as a weapons testing ground, bombing and artillery range, ordnance disposal site, and military reservation. The installation hosts the Philippine Air Force 710th Special Operations Wing. Capabilities include aerial combat training, bombing and strafing practice, ground unit maneuvers, and live-fire artillery exercises.
