In West Germany, the Navy has adopted MPL, and some police agencies, just like the West Berlin Police, adopted either MPL, MPK and/or both. During the 1972 Munich Olympics and the ensuing terrorist incident, the local police was equipped with the MPL. However, most of the police officers dispatched at this time were only trained as patrol police officers and had little experience in using the MPL. The counter-terrorist unit GSG-9, which was established after the incident, adopted the H&amp;K MP5 as their service submachine gun instead of the Walther MP. As spread of MP5 began, it would begin to eclipse the Walther MP's sales until the Walther product was discontinued.
