The urbanization of warfare has necessitated the kind of precision targeting that only small arms can deliver. Weapons not often seen on the battlefield can prove useful, even indispensible, in an urban setting. This expert reference guide examines in detail the most successful small arms in use and how changes in warfare have affected how those weapons are used and have transformed the small arms industry. Professional soldiers, law enforcement officers and students and researchers of small arms will gain a working knowledge of the most common and successful urban combat weapons (including some currently in development).
