A linked round carrying bag having a flexible sleeve and a fastening is provided. The sleeve is sealed at a first end, has an opening at a second end, and has an openable closure, for example, a zip, extending substantially from the first end to the second end. A width of the sleeve is greater than the length of an individual round of the linked round that the bag is designed to carry but is less than twice the length of an individual round. The fastening is adjacent a closed side of an opening of the sleeve and is arranged to be tightly fastenable around the closed side of the opening and any linked round carried in the bag. The fastening can ensure that a linked round is held in its proper position within the bag, even when the bag is carried as a bandolier.

A reciprocally-cycled weapon delinks and fires cartridges in open-end linked ammunition belts or close-end linked ammunition belts. The weapon has first round select and first cycle fire capabilities. The bolt carrier assembly translates out of phase with the extractor assembly. The extractor assembly is configured for rearward extraction of the cartridges in close-end linked ammunition belts. The weapon works seamlessly with open-end linked and close-end linked ammunition belts.

An ammunition magazine is used with a reciprocally-cycled weapon for delinking and firing cartridges in close-end linked ammunition belts. The magazine includes a housing with an ammunition indexing mechanism fixed to one side of the housing. A magazine feed box is disposed above the ammunition indexing mechanism. The magazine feed box includes a movable follower having an upper and a lower position and cam pins that engage cam slots in the magazine feed box. The movable follower is configured to receive a cartridge from the weapon.

A vehicle-mounted weapon station is configurable to adjust the height of a rotational elevation axis thereof. The weapon station is provided with at least one fixed hanging ammunition container that is reloadable under the armored protection of the vehicle and the weapon station shell. The weapon station may have both electrically-powered and manually-powered drive systems for rotating a pedestal about an azimuth axis relative to the vehicle, and for rotating weaponry and operational units about the elevation axis, wherein the electrical and manual drive systems transmit power through the same output gear.

An externally-operated weapon has a direct current servo motor that provides motive force to drive the weapon operating group at an average rate of fire. Within a single cycle, the weapon operating group is driven at rates greater than and less than the average rate of fire, while the overall rate for a single cycle is maintained at the average rate of fire. Some benefits of servo motor control include reduced power consumption, increased bolt dwell time, expansion of the weapon's battlefield role from one to many roles, and increased accuracy and shot-to-shot precision while firing from an open bolt position.

Disclosed is a cartridge for an air gun that facilitates the loading of a bullet into the cartridge. The cartridge includes cylindrical unitary cartridges into which bullets are to be inserted, a cartridge assembly in which the unitary cartridges are coupled to each other and continuously disposed between both ends to form a strip shape, and a magazine case that houses the cartridge assembly. The cartridge assembly is transported by a cartridge transport unit. Further, the unitary cartridges each include two cylindrical parts. The cylindrical parts of neighboring unitary cartridges are sequentially fit-coupled to each other in order to form the cartridge assembly.

A tow plate and active vibration control (AVC) housing configured to couple to a helicopter sponson about an AVC and support a gun mounting system.
