In the 1970s West Berlin stood 100 miles inside communist-controlled territory, a tragically flawed testament to post-World War II geopolitical acrimony. The Berlin Brigade was a token NATO force billeted in this surrounded, beleaguered city. Their mission was not so much their combat effectiveness as it was what they represented. Attacking the Berlin Brigade was tantamount to attacking the United States. However, chances are things would not have ended well for these isolated grunts had the Cold War suddenly turned hot.
Operating in the shadows in West Berlin was a small contingent of Special Forces soldiers known as Detachment A. Theirs was the archetypal Green Beret mission. Should the balloon go up and Warsaw Pact forces roll over West Berlin like a juggernaut, Detachment A troops would melt into the population to foment a covert underground war. To pull this off, these iron-willed studs had a 10,000-weapon stash of military firearms hidden for distribution to would-be partisans. Thank the Good Lord it never came to pass.
There were never more than about a hundred Special Forces operators assigned to Detachment A. Given the unique nature of their mission they were authorized some comparably unique weapons. One of those unique firearms was the Walther MP submachine gun.
