William Weir, author of New Page Book's 50 Battles That Changed the World, takes another look at the history of warfare, focusing on the hardware that served those famous battles, as well as others not as glorious. Included are: * Individual weapons-from spears to the submachine gun. * Crew-served weapons-from battering rams to "Big Bertha". * Unmanned weapons-from punji stakes to "Bouncing Betty" landmines and trap guns. 50 Weapons That Changed Warfare even includes devices that, strictly speaking, are weapons carriers, such as tanks and bombers, but which have had enormous effects on the conduct of war.
