Heckler &amp; Koch MP2000 The Heckler & Koch MP2000 was an attempt to improve the MP5 series. Prototypes of the gun showed similarities to the UMP. An interesting feature of this gun was that it featured a silencing system which prevented the bullet from reaching supersonic speeds by venting some of the propellant gases. The gas vent hole could be closed in order to achieve normal bullet velocities.

.30-40 Krag The .30-40 Krag (also called .30 U.S., or .30 Army) was a cartridge developed in the early 1890s to provide the U.S. armed forces with a smokeless powder cartridge suited for use with modern small-bore repeating rifles to be selected in the 1892 small arm trials. Since the cartridge it was replacing was the .45-70 Government, the round was considered "small-bore" at the time. The design selected was ultimately the Krag–Jørgensen, formally adopted as the M1892 Springfield. It was also used in M1893 and later Gatling guns.

Ordnance QF 17-pounder The Ordnance Quick-Firing 17-pounder (or just 17-pdr) was a 76.2 mm (3 inch) gun developed by the United Kingdom during World War II. It was used as an anti-tank gun on its own carriage, as well as equipping a number of British tanks. It was the most effective anti-tank gun of the war fielded by the Western Allies (that is, excluding the Soviet Union). Used with the APDS shot, it was capable of defeating all but the thickest armour on German tanks. It was used to 'up-gun' some foreign-built vehicles in British service, notably to produce the Sherman Firefly variant of the US M4 Sherman tank, giving British tank units the ability to hold their own against their German counterparts. In the anti-tank role, it was replaced after the war by the 120 mm BAT recoilless rifle. As a tank gun, it was succeeded by the 84 mm 20 pounder.

8mm Roth–Steyr The 8mm Roth–Steyr is a military centerfire pistol cartridge adopted by the Austro-Hungarian cavalry in 1907 for the "Repetierpistole" M7—the first self-loading pistol adopted by a major military power. The cartridge headspaces on the mouth of the case. Ammunition was typically packaged in a unique ten-round charger. Austrian military production contained greased un-plated steel-jacketed bullets. A few private firms in Austria manufactured ammunition with cupro-nickel-jacketed bullets. Fiocchi Munizioni manufactured 8mm Roth–Steyr cartridges as one of its specialty lines as recently as 2017. An alternative source of reloadable cartridge cases is a labor-intensive process of base forming, trimming, neck reaming and resizing .30 Carbine brass.

M203 grenade launcher The M203 is a single-shot 40 mm under-barrel grenade launcher designed to attach to a rifle. It uses the same rounds as the older stand-alone M79 break-action grenade launcher, which utilizes the High-Low Propulsion System to keep recoil forces low. Quite versatile, and compatible with many rifle models, the M203 was originally designed for the U.S. M16 and its variant, the M4 Carbine. The launcher can also be mounted onto a C7, a Canadian version of the M16 rifle, however, this requires the prior removal of the bottom handguard.

Type 80 machine gun The Type 80 () is a general-purpose machine gun manufactured by Norinco in the People's Republic of China, based on the Russian Kalashnikov PKM series. The machine gun was certified for design finalisation in 1980 and entered the PLA service in the mid-1980s, specifically in 1983. The Type 80 was intended as a successor to the Chinese independently developed Type 67, doing well in tests conducted in the Chengdu Military Region before it was dropped and instead, opted to keep the Type 67 GPMG in use. Only a few Type 80s were used in the People's Liberation Army Marine Corps and a modified Type 80, named as Type 86, was then accepted by PLA armor units.
