Mikhail Kalashnikov, designer of the world's most popular assault rifle, says that U.S. soldiers in Iraq are using his invention in preference to their own weapons, proving that his gun is still the best.

"Even after lying in a swamp you can pick up this rifle, aim it and shoot. That's the best job description there is for a gun. Real soldiers know that and understand it," the 86-year-old gunmaker told a weekend news conference in Moscow.
