[1] Although the new GNL was to be exclusively composed by Laotian nationals,[2] it was kept under the close supervision of French gendarmes from the Republican Guard units stationed in Indochina.

[6] The new Lao Gendarmerie was charged with safeguarding internal security and public order, with a planned strength of 1,250 officers and enlisted men, though the actual number was lower.

[9] The new unit soon became involved in Laos' domestic politics during the turbulent period of the early 1960s, with its commander Lt. Col. Siho actively conspiring in Major general Phoumi Nosavan's return to power.

[11][12] For his actions in support of his patron Major general Phoumi Nosavan's December 1960 countercoup, Lt. Col. Siho was rewarded with a promotion to Brigadier general and given command of a new paramilitary security organization:[13] in March 1961 the GMS 1 was combined with Laotian National Army or ANL (military intelligence, psychological warfare, and military police units) and PRL (the civil police force and the immigration service) units to form the DNC.

Gen. Siho and its new security agency quickly took over police duties in Vientiane, exercising near absolute authority in the capital city and began screening the civilian population for Pathet Lao elements and stragglers, which often led to abuses.

[17] In reality, the GMS served principally as Siho's personal bodyguard, gaining a reputation among the civilian populace for both corruption in police duties and military ability as para-commandos.

Gen. Siho appointed Lieutenant colonel Thao Ty as his replacement at the head of the GMS 1 para-commando regiment, while retaining the command of the DNC.

Gen. Siho was forced to exile in Thailand[25] and his DNC 'empire' was quickly divided, with its units being disbanded: the military intelligence, psychological warfare, and military police personnel were returned to the RLA structure whilst some of the policemen were kept in service and renamed the National Police Corps, which was assigned to the Ministry of the Interior of the Royal Lao Government.

In addition, selected PRL personnel were also sent to the United States, the Philippines, Thailand, Singapore, Hong Kong and Malaysia to attend specialized courses.

[45] Initially, GMS paratroopers of the DNC wore dark blue fatigues, whose cut followed closely that of the U.S. Army OG-107 jungle utilities, to distinguish them from the rest of the Royal Lao Armed Forces (FAR).

[13] Royal Lao Police peaked caps were worn with the standard metal PRL cap device, a silver bow and arrow per pale charged with the Airavata crest bearing the Laotian Royal Arms (Erawan) – a three-headed white elephant standing on a pedestal and surmounted by a pointed parasol – inserted on a gilt wreath representing flames emerging from a Lotus leaf rosette below.

GMS web gear In the field was a mix of U.S. M-1945 and M-1956 load-carrying equipments (LCE), respectively in khaki and olive green cotton canvas and standard issue in the FAR.

[46] Unlike the FAR, the GMS and DNC never developed a distinctive unit insignia nor a beret badge, and even rank insignia was seldom seen on uniforms; a commemorative embroidered red round patch edged black bearing a tiger surmounted by the Laotian inscription "Revolutionary Forces" (Lao: ກຳ ລັງປະຕິວັດ | kam lang pativad), which celebrated Siho's recapture of Vientiane in 1960, was worn on the left shoulder.

In 1962 the DNC adopted a distinctive set of gold parachute wings in three classes modelled after the PARU airborne qualification badge, which were worn above the right pocket of the fatigue shirt.
