During the 1970s, force protection concerns grew as Palestinian groups brazenly conducted terror operations in Europe, such as the kidnapping of Israeli athletes during the 1972 Munich Olympics, and the Red Army Faction and the Red Brigades targeted U.S. facilities and personnel with bombings, kidnapping and assassinations. In May 1972 bombs exploded at V Corps headquarters in Frankfurt, killing an Army lieutenant colonel, and in Heidelberg at Campbell Barracks, killing three Soldiers. U.S. installations were attacked sporadically throughout the remainder of the decade, including a failed 1977 attack on a U.S. Army post in Giessen. On 15 September 1981, an assassination attempt was made on USAREUR commander Gen. Frederick J. Kroesen and his wife as they were driving through Heidelberg—the automobile trunk lid deflected the RPG-7 anti-tank projectile. In 1985 Army Specialist Edward Pimental was lured out of a Wiesbaden nightclub and killed for his ID card which was then used to enter Rhein-Main Air Base the next day to plant a bomb that killed two. And in 1986 a bombing at a Berlin disco frequented by service members killed two Soldiers. With increased combat and support components in place, the command undertook a wide-ranging modernization in the decade of the 1980s. More than 400 new systems were introduced, including individual weapons, field rations, the M1A1 Abrams tank, the M2 and M3 Bradley series of infantry and cavalry fighting vehicles, the MLRS M270 multiple launch rocket system, the MIM-104 Patriot air defense system, the UH-60 Black Hawk helicopter and the AH-64A Apache helicopter. In January 1967, in accordance with Headquarters Department of the Army Msg NR DA796059 dated 9 January 1967, the USAREUR and Seventh Army staffs were merged to become Headquarters and Headquarters Company, United States Army Europe and Seventh Army (HHC USAREUR 7A). The dramatic events of the late 1980s – the opening of the Berlin Wall, German reunification, and the collapse of the Soviet Union – combined to change USAREUR again. Intermediate nuclear weapons of the 56th Field Artillery Command were withdrawn, chemical weapons were moved out of Europe, and units began to depart the European continent while others were inactivated. When Iraq invaded Kuwait in August 1990, USAREUR began deploying units to the region. The first deployments from USAREUR to Saudi Arabia in August 1990 included the 45th Medical Company, an element of the 421st Medical Battalion (AA), and advance elements of 12th Aviation Brigade, which by September had deployed two Apache attack helicopter battalions, a Kiowa scout helicopter company, a Black Hawk utility helicopter company, a Chinook platoon, and associated support and maintenance units.
