Document 2: Heckler &amp; Koch MP7: The Heckler & Koch MP7 "(Machine Pistol 7)" is a German Personal Defence Weapon (PDW) designed and manufactured by Heckler & Koch (H&K) and chambered for the HK 4.6×30mm cartridge. It was designed with the new cartridge to meet NATO requirements published in 1989, as these requirements call for a personal defense weapon (PDW) class firearm, with a greater ability to penetrate body armor than current weapons limited to conventional pistol cartridges. The MP7 went into production in 2001. It is a direct rival to the FN P90, also developed in response to NATO's requirement. The weapon has been revised since its introduction and the latest production variants are the MP7A1 and MP7A2.<ref name="Heckler & Koch HK MP7 Submachine Gun / Machine Pistol July 30, 2012"> </ref>

Document 5: Solothurn S-18/100: The Solothurn S-18/100 20 mm anti-tank cannon was a German and Swiss anti-tank rifle used during the Second World War. It had a semi-automatic action in a bullpup configuration. As a result of its large, powerful ammunition, the gun had a tremendous recoil, and its size made portability difficult. The feed was either from a five or (more usually) ten-round magazine that was attached horizontally to the left side of the gun. The gun used 20×105mm belted-case ammunition which it shared with the S 18-350 aircraft cannon that was developed from the rifle. A Finnish source gives armour penetration of the gun (probably achieved with the Hungarian APHE-T round, since it was the only type used in Finland) as 20mm at a 60-degree angle at 100-metre distance, decreasing to 16mm at 500 metres.
Document 6: MG 29: The Flieger MG 29 (also called the Flab MG or FLab MG 29/38) was a Swiss light machine gun developed in the 1920s and produced until shortly before the dawn of the Second World War. It was mounted on aircraft and was later used as an anti-aircraft gun. However, it was too heavy to be used as am infantry support weapon. It employed a closed bolt system. Some guns had the ability to bolt a large box onto the bottom of the machine gun to hold the ammunition belt. Two versions of the gun existed, the "normal" version and a second version which bolted two guns together and made them to fire from the same trigger, known as the "Doppel-MG" (double machine gun). After the second world war, better anti aircraft systems and aircraft weapons were available to Switzerland and the infantry support role was filled by the MG 51. The higher rate of fire, but much heavier MG 29 was finally mounted on the first prototype of the Panzer 58, the precursor to the more famous Panzer 61 tank before being retired.
Document 7: Leopard 2: The Leopard 2 is a main battle tank developed by Krauss-Maffei in the 1970s for the West German Army.

Various versions have served in the armed forces of Germany and 12 other European countries, as well as several non-European nations, including Canada (Leopard 2A4m can), Chile, Indonesia, Singapore and Turkey. The Leopard 2 was used in Kosovo with the German Army and has also seen action in Afghanistan with the Danish and Canadian contributions to the International Security Assistance Force, as well as seeing action in Syria with the Turkish Armed Forces against IS and the YPJ.
Document 8: Schützenpanzer Lang HS.30: The Schützenpanzer Lang HS.30 (also "Schützenpanzer 12-3") was a West German infantry fighting vehicle developed from 1956 to 1958. It was a Swiss Hispano-Suiza design, with a Rolls-Royce engine. After some early mechanical problems only 2,176 were built of the 10,680 planned. It was armed with a 20 mm cannon which was an unusually powerful weapon for an armoured personnel carrier of the period. Its design proved to have many flaws and drawbacks and the construction was followed by a great political scandal in West Germany in the 1960s. 2,176 SPz 12-3 and variants were built until 1962, for which the German government paid 517 million DM, or about 238,000 DM per vehicle. The SPz 12-3 first entered service with the "Panzergrenadier" battalions in 1960 and was replaced by the Marder infantry fighting vehicle from 1971.

Document 10: History of BMW: BMW AG originated with three other manufacturing companies, Rapp Motorenwerke and Bayerische Flugzeugwerke (BFw) in Bavaria, and Fahrzeugfabrik Eisenach in Thuringia. The company is now known as BMW or Bayerische Motoren Werke. Aircraft engine manufacturer Rapp Motorenwerke became Bayerische Motorenwerke in 1916. The engine manufacturer, which built proprietary industrial engines after World War I, was then bought by the owner of BFw who then merged BFw into BMW and moved the engine works onto BFw's premises. BFw's motorcycle sideline was improved upon by BMW and became an integral part of their business.

The Panzerfaust 3 is operated by at least 11 countries and has been employed in Afghanistan.
Document 13: Hispano-Suiza 12N: The Hispano-Suiza 12N was one of two new V-12 engine designs first run in 1928 and was manufactured by Hispano-Suiza's French subsidiary for the Armee d'l'Air. It produced about 485 kW , was the first to use gas nitride hardening and introduced wet cylinder liners into Hispano-Suiza's aircraft engine range. It powered the first non-stop flight from Europe to the United States.
Document 14: GT 101: The GT 101 was a turboshaft-type gas turbine engine developed from the BMW 003 aviation engine, that was considered for installation in Nazi Germany's Panther tank. The German Army's development division, the "Heereswaffenamt" (Army Ordnance Board), studied a number of gas turbine engines for use in tanks starting in mid-1944. Although none of these was fitted operationally, the GT 101 (GT for "Gas Turbine") reached a production quality stage of development. Several designs were produced over the lifetime of the program, including the GT 102 and GT 103.
