Short answers, pulled from the story.
The Pershing II was a solid-fueled, two-stage medium-range ballistic missile built by Martin Marietta as the United States Army's primary nuclear-capable theater-level weapon. It replaced the Pershing 1a, entering service in 1983.
The first Pershing II launchers arrived in West Germany in late November 1983, with deployment completed in late 1985 at a total of 108 launchers. Initial Operational Status was reached on the 15th of December 1983 at Mutlangen.
The Pershing II used an active radar guidance system that compared live radar video to pre-stored reference scenes of the target, giving it an accuracy of 30 m circular error probable. If that radar guidance failed, inertial navigation kept the missile on target with reduced accuracy.
The deployment of Pershing II and GLCM missiles triggered some of the largest protests of the Cold War, many organized by the Campaign for Nuclear Disarmament. About 300,000 protesters gathered in Bonn in October 1981, and as many as 500,000 protested there again in October 1983, including a human chain from Stuttgart to Neu-Ulm.
On the 11th of January 1985, a fire at Camp Redleg near Heilbronn killed three soldiers of C Battery, 3rd Battalion, 84th Field Artillery Regiment while a missile stage was being removed from its storage container. Investigators found that the Kevlar rocket casing had built up a triboelectric charge in cold, dry weather, which ignited the propellant.
After the Intermediate-Range Nuclear Forces Treaty was ratified on the 27th of May 1988, the Pershing II missiles were withdrawn starting in October 1988. The last were destroyed by static-burning and crushing their motors by May 1991 at the Longhorn Army Ammunition Plant near Caddo Lake, Texas.
