105 mm and 155 mm towed howitzers, 106 mm recoilless rifles, 90mm guns and BGM-71 TOW platforms. In the 1990s, the V-150s were replaced in the mechanized battalions with over LAV-25 Family of Vehicles bought from DDGM/GD in Canada. The second component of the national guard, made up of tribal battalions under the command of local sheikhs, was organised into four infantry brigades (called the Fowj). These men, often the sons of local chiefs or of veterans of the original Ikhwan forces, reported for duty about once a month for the purpose of receiving stipends. They were provided with Heckler & Koch G3 rifles, although many had individually acquired AK-47s and other automatic weapons. They also have radios and are equipped with Toyota pickup trucks or Land Rovers. Many units are stationed along the borders of the Kingdom and have the mission to patrol the border areas. Although neither particularly well trained nor well equipped, they could be counted on to be loyal to the House of Saud if called for service. Their enrollment in the guard was largely a means to bolster the subsidies paid to local shaykhs and to retain the support of their tribes. The national guard's King Abdulaziz Mechanized Brigade was swiftly deployed to the border area after Iraq's invasion of Kuwait in 1990 and was actively engaged in the war, notably in the fighting to retake the town of Ra's al Khafji. After the war ended, it was reported that an enlargement of the national guard to eleven or twelve active brigades was contemplated. In addition, the ageing Commandos were to be replaced by more than 1,000 eight-wheeled LAV-25s and LAV variants manufactured by General Motors in Canada. The LAVs were to be mounted with a variety of armaments, such as 25 mm autocannon, larger-calibre 90 mm guns, 120mm mortars and TOW missile launchers. Command The Saudi Arabian National Guard's communications and chain of command maintained a separate network from regular Saudi Arabian military channels with a senior member of the royal family as its head. This structure was established by King Saud in 1956. Prior to 1956 the Guard was led by tribal sheikhs. Following the 1956 reorganization the first royal, Khalid bin Saud who was King Saud's son, was assigned to command the Guard in July 1957. In 1959 Saad bin Saud, another son of King Saud, became the commander. King Abdullah commanded
