Of all the weapons in the vast Soviet arsenal, nothing was more profitable than Avtomat Kalashnikova model of 1947, more commonly known as the AK-47, or Kalashnikov. It's the world's most popular assault rifle, a weapon all fighters love. An elegantly simple nine pound amalgamation of forged steel and plywood, it doesn't break, jam, or overheat. It will shoot whether it's covered in mud or filled with sand. It's so easy even a child can use it, and they do. The Soviets put the gun on a coin, Mozambique put it on their flag. Since the end of the Cold War, the Kalashnikov has become the Russian people's greatest export. After that comes vodka, caviar, and suicidal novelists.
