The Royal Lao Army (; – ARL), also designated by its anglicized title RLA, was the Land Component of the Royal Lao Armed Forces (FAR), the official military of the Kingdom of Laos during the North Vietnamese invasion of Laos and the Laotian Civil War between 1960 and 1975.
History
The ARL traced back its origins to World War II, when the first entirely Laotian military unit, the 1st Laotian Rifle Battalion ( – BCL), was raised early in 1941 by the Vichy French colonial authorities. Intended to be used on internal security operations to bolster the local colonial constabulary force, the "Indigenous Guard" (), the 1er BCL did not see much action until after March 9, 1945, when the Japanese Imperial Army forcibly seized control of French Indochina from France, including Laos. The battalion then retreated into the mountains, where they linked with the Laotian irregular guerrilla fighters () operating there. These guerrillas were supplied, trained, and led by teams of Free French agents who had been trained in special jungle warfare by the British Special Operations Executive (SOE) in India and were subsequently parachuted into Indochina in December 1944 with the aim of creating a local anti-Japanese resistance network. Under the command of their Free French cadres, the battalion's Laotian soldiers engaged in guerrilla actions alongside the irregular "Maquisards" against the Japanese occupation forces in Laos until Japan's surrender on August 15, 1945. In November of that same year, the various Laotian guerrilla groups were consolidated into four regular light infantry battalions and, together with the 1er BCL, integrated into the newly founded French Union Army.
Meanwhile, confronted in early May 1945 with the Allied Powers' victory over Nazi Germany and sensing their own imminent defeat, the Japanese military authorities in Laos began stirring up local anti-French nationalistic sentiments. In October of that year, a group of supporters of Laotian independence led by Prince Phetsarath Ratanavongsa deposed King Sisavang Vong and announced the formation of a new government body, the Committee for Independent Laos () or Khana Lao Issara and Lao Issara for short. Taking advantage of the temporary absence of French authority in the country's main cities, the Lao Issara promptly established an armed defense force to exercise its authority with the support of Ho Chi Minh's Viet Minh Hanoi-based government in the Tonkin and the Nationalist Chinese. The Lao Issara "Army" was essentially a lightly armed militia force, provided with a mixed assortment of small-arms captured from the Japanese, looted from French colonial depots, or sold by the Chinese Nationalist Army troops who occupied northern Laos under the terms of the 1945 Potsdam Conference.
The National Laotian Army 1946–1955
In early March 1946, the French Union Army aligned some 4,000 Laotian troops organized into five light infantry battalions () – the 1er, 2e, 3e, 4e, 5e, and 6e BCLs – led by a cadre of French officers and senior NCOs, which participated actively in the French reoccupation of Laos. That month, the Laotian battalions provided infantry support to French Far East Expeditionary Corps (CEFEO) armoured units fighting Lao Issara troops at the Battle of Thakhek in Khammouane Province. By the end of April, they had assisted the French in the recapture of Vientiane, followed in May by Luang Prabang which forced the Lao Issara leadership to flee to exile in Thailand. Upon the successful conclusion of the campaign, the Laotian battalions continued with small counter-insurgency operations against remnant bands of Lao Issara insurgents over the next three years, assuming responsibility for internal security duties in the areas located along the Thai border.
However, faced with the potential threat posed by the growing Viet Minh insurgency in neighbouring Vietnam, the French instituted on July 1, 1949, a separated National Laotian Army ( – ANL) of the French Union to defend Laos. Its formation actually began earlier in 1947 as an informal gathering of several indigenous irregular auxiliary units made of ex-Lao Issara guerrillas raised early by the French to reinforce their regular CEFEO units.
In July 1959, the ANL, the Laotian Navy, and the Laotian Aviation were gathered into the newly created Laotian Armed Forces ( – FAL), renamed Royal Lao Armed Forces ( – FAR) in September 1961.
Structure
The chain of command of the Royal Lao Army was placed under the Ministry of Defense in Vientiane. The country was divided into five military regions, roughly corresponding to the areas of the country's 13 provinces.
