Volume Five of the critically acclaimed series Big Bang: The Mostly Illustrated RPG Guide to Modern Weapons is now available at www.rpgnow.com . This latest installment focuses mainly on grenades used by the old Cold War opponents, the United States and the Soviet Union. More than 50 different grenades are detailed. And if you thought all grenades worked the same, this book will certainly change your mind. Included is a short primer on riot control agents, the chemical weapons used to break up unruly mobs, violent riots and less than peaceful demonstrations.
