It was a light anti-aircraft gun used by Germany in World War II. Designed by Rheinmetall, it is an improved model of FLAK30 to improve the rate of fire. The design began in the late 1930 s, and in 1939 it was accepted as the standard anti-aircraft gun for the German Army and was used extensively throughout the war. Used as a single-barrel towed gun, it was also installed on a variety of vehicles and fixed positions, including a quadruple-mounted version, which greatly enhanced anti-aircraft fire. Because of its excellent performance and high rate of fire, it became a nightmare for the Allied Air Force.

The 9mm submachine gun designed and manufactured by the German company Heckler&Koch has been known for its high firing rate, low recoil, and shooting accuracy since its development in the 1960s. The MP5 series includes multiple models, such as MP5A3, MP5SD micro acoustic model, and MP5K ultra short model, to meet different tactical needs. Adopting the same roller locking system as the G3 rifle ensures reliability and safety. Widely adopted by military and police forces in over 50 countries worldwide, it has become a signature weapon in counter-terrorism and special operations. Its magazine capacity is usually 15 or 30 rounds, with an effective range of 200 meters. Easy to carry and hide.
