Military engineers – as opposed to “combat” engineers who are crazy enough to rush into battle carrying tools and explosives rather than weapons – are tasked with building fortifications and other structures and creating and maintaining lines of supply and communication. The most victorious armies of the past – Roman, Chinese, Ottoman, British, etc. – all had superior military engineering units, to which much of their success was owed, both for protecting their own troops and knocking down the enemy’s defenses. Just ask the Gauls at Alesia (52 BC) or the Zealots at Jerusalem (70 AD). Following the fall of Rome in the west, military engineering – like just about everything else – entered a “dark age,” not to be revived until the mid-Middle Ages, when once again sieges were prevalent. By the end of the age, military engineers were again an integral part of any victorious army. Throughout the Napoleonic, Crimean, various civil and world wars, military engineers were divided into ever-more specialties. These days, a military professional needs a degree in civil, electrical, mechanical, architectural or even environmental engineering to be given the chance to build things...or tear them down.
