Historically, crossbows played a significant role in the warfare of East Asia, Europe and the Mediterranean. The invention of the crossbow caused a major shift in the role of ranged weaponry among armies, as the traditional bow and arrow had long been a specialized weapons system which required a considerable degree of lifetime training, physical strength and expertise to operate with any degree of efficiency; in many cultures, despite being usually drawn from the common class, bowmen were considered a separate and superior caste, as their archery skill-set was essentially developed from birth and impossible to reproduce outside a pre-established cultural tradition, which many nations lacked. In modern times, although largely supplanted by firearms in most roles, crossbows are still widely used for shooting sports, hunting, and when shooting in relative silence is an important consideration.
