Readers learn about aircraft, battleships, gas, pistols, rifles, and more. World War I combatants were the first to use planes and tanks, items that were improved upon greatly in later conflicts. Weapons in the Vietnam War included chemical weapons designed to destroy vegetation, the M79 Grenade Launcher, and the Cold War featured spy satellites. Enthusiasts of military history and weapons will appreciate the statistics included, such as that the F-15 Eagle had a 104–0 "kills" record, triplanes could climb to 20,000 feet, and the M79 Grenade Launcher could fire grenades up to 385 yards.
