A method of denying access to a designated area (10) wherein said method includes monitoring the designated area (10) to detect the presence of an intruder, and initiating an attack on said intruder by discharging projectiles (15) from a barrel assembly (13). Barrel assembly (13) includes one or more barrels (16), a plurality of projectiles (15) axially disposed within each barrel (16) for operative engagement with the bore of barrel (16), and discrete propellent charges for propelling respective projectiles (15) sequentially through the muzzle of barrel (16). The monitoring can be performed (15) remotely from designated area (10) by sensing means (14), or on-site by way of sensors (11) distributed within designated area (10). The intruder can be military personnel such as one or more infantrymen, or a manned or unmanned vehicle such as an armoured car or tank.
