The Royal Netherlands Army Artillery provides artillery support for the Royal Netherlands Army. It is divided into three corps, undertaking two roles: Korps Veldartillerie - Field Artillery and Korps Rijdende Artillerie - Horse Artillery. These two corps undertake the field artillery role. They are equipped primarily with the PzH2000 and were equipped with the M109 howitzer. Until 2013, one regiment retained the traditions of the Veldartillerie and one of the Rijdende Artillerie, with one assigned to each of the army's mechanised brigades. In 2013, following a series of defence cuts, the two artillery regiments were amalgamated into a single unit called the Fire Support Command (VuursteunCommando), with three fire support batteries and an HQ battery, of which two of the fire support batteries are Veldartillerie and one, together with the HQ is Rijdende Artillerie. Korps Luchtdoelartillerie The third corps is Korps Luchtdoelartillerie - Air Defence Artillery. It undertakes the air defence role. Three individual batteries were equipped with Stinger man-portable air defence missiles and the Cheetah armoured air defence vehicle (a variation of the Leopard 1) and are assigned to the three mechanised brigades. The rest of the unit is assigned to provide air defence for other vital areas. Korps Luchtdoelartillerie consists of the Air Defence Command (Commando Luchtdoelartillerie). 11 Air Defense Company (Air Assault) Samarinda (part of 11 Luchtmobiele Brigade) is considered part of the Air Defense Artillery Regiment, but is an independent Air Defense Company and part of the infantry Regiment Van Heutsz. It is composed mostly of infantry. To avoid confusion, it was named a company rather than a battery. As of 2007 the Air Defence Command (Colua) is located at [De Peel Air Base] and equipped with the NASAMS 2 Army Ground Based Air Defense Systems (Army GBADS). The regiment consists of a Joint Air Defense Center, a Staff battery, 11th Air Defense battery, 13th Air Defense battery, an instruction and training battery and the Joint Air Defense School. Each of the two Air Defense batteries consists of a staff platoon, three Stinger Weapon Platform platoons and a NASAMS 2 Fire Unit (FU). The SWP are available in two variants: The SWP [Fennek] is a four wheeled armored vehicle with the [Aselsan] ready to fire a Stinger surface-to-air missile launcher. The Mercedes Benz G290GD four-wheel drive light transport vehicle, with a Dual Mounted Stinger (DMS) on a tripod, offers two Stingers ready to fire. By integrating
