Republic of Vietnam National Police Field Force

The Republic of Vietnam National Police Field Force (Cãnh Sát Dã Chiên – CSDC), also designated ‘Police de Campagne’ by the French and variously as ‘National Police Field Force’ (NPFF), or ‘Field Force’ for short by the Americans, was a paramilitary élite branch of the Republic of Vietnam National Police (Vietnamese: Cãnh Sát Quốc Gia – CSQG). Active during the Vietnam War, the CSDC operated closely with the Army of the Republic of Vietnam (ARVN) and the American Central Intelligence Agency (CIA) from 1966 to 1975.

History
The CSDC was created in January 1966 by the South Vietnamese government as an armed support unit for the National Police.

Missions
The role of the CSDC went well beyond the normal duties of a civil police force, functionally serving as another branch of the armed forces. National Field Police units were often the first to arrive to the scene in engagements, particularly in cities and population centers.

Structure and organization
The Field Police Command Staff reported directly for operational orders to the National Police Command and was co-located to the CSQG Headquarters at Saigon. Under the designation of ‘Armed Support Unit’, the CSDC Command in 1969 was in charge of the Field Police units and of the River and Coastal Police. Rechristenized ‘Reaction Unit’ in 1972, the Field Police Command integrated the Provincial Investigation Force and in 1973 changed again its designation to ‘Mobile Operations Department’.

The basic unit of the Field Police was the company (Vietnamese: Dai Đội – DD), organized into a 24-man company headquarters (HQ) and several 40-man combat platoons (Vietnamese: Trung Đội – TRD), each with four 10-man squads (Vietnamese: Tiệu Đội). Until 1968, one company was assigned to each province and main cities and fielded a number of platoons ranging from two to 13 according to the number of rural or urban districts. For example, up to five districts a single company was assigned, but if a province or town counted more tham six districts, two companies could be deployed. After 1969 however, a major re-organization was implemented, with the provincial companhies being expanded into battalions (Vietnamese: Tiệu Doàn – TD). By August 1971, the CSDC strength totalled 16,500 officers and enlisted men organized into 44 provincial battalions comprising some 90 companhies, 242 district platoons and one independent armoured cavalry platoon. Two independent companhies of four platoons each were based respectively at Vung Tau and Da Nang, two autonomous port cities which had their own municipal police services separated from the province in which they were located.

To provide supervision and support to all these provincial and urban Field Police units, Regional Headquarters and Service Companies were located at each of the country’s four Military Regions. A CSDC company was usually commanded by an Inspector (a Capitan after 1971), who came under the operational command of the National Police provincial chief whilst platoons assigned to the districts were firmly under operational control of the district police chief who, in turn, was directly answerable to the district political chief.

Armoured car unit
A predominantely light infantry force, the CSDC operated a single independent armoured cavalry platoon, provided with eight World War II-vintage US M8 Greyhound light armoured cars. Headquartered at Saigon, it was tasked of providing security to the National Police HQ and the adjoining National Bank building and their environs.

Tactical Mobile Groups
In addition, the Field Police maintained two Tactical Mobile Groups – TMG  (Vietnamese: Biêt Doàn – BD) totalling 5,000 men and designated BD 5 and BD 222 respectively, which conferred the National Police the capacity to engage independently in either defensive or offensive actions according to its mission of operational defense.

Based at Saigon, BD 5 was in fact an enlarged battalion since it fielded, in addition to one headquarters’ (HQ) company, 12 to 14 combat companies of four platoons each. The battalion operated on the wider Saigon-Gia Dinh region, assigned to the Saigon Municipal Police Directorate which was encharged with the internal security and internal defense of the nation's Capital City. During the Tet Offensive in January 1968 the unit was committed in the defense of President Nguyễn Văn Thiệu residence, the Independence Palace alongside other National Police and ARVN units, distinguishing itself in the fighting around Tan Son Nhut Air Base and Cha Tam Church, where they inflicted heavy losses on attacking Vietcong (VC) units.

Also headquartered at Saigon, BD 222, a smaller battalion with just six combat companies, was in turn assigned to the General Reserve of the National Police as a quick reaction unit that could be deployed nation-wide, being tasked with specific missions and reinforcement duties. Engaged in Saigon during the Tet in 1968, the field policemen of BD 222 succeeded in flushing out the VC Sappers entrenched in the National Radio Broadcasting Station building, located a few hundred meters away from the American Embassy, but also fought elsewhere. Between 1968 and 1975, the Battalion's combat companies were deployed at various times and locations throughout the country, engaging in defensive and offensive operations in conjunction with other National Police or ARVN units at Huế, Da Nang, Bình Định, Tuyen Due, Gia Dinh, Long An, Biên Hòa, and Phu Quoc Island. When the city of An Lộc was besieged in April 1972 during the Easter Offensive by three NVA armoured divisions, BD 222 was rushed in to bolster the city's defenses and successfully held its ground against repeated assaults by enemy tanks.

Training
National Policemen who volunteered to Field Force service, in addition to their basic police instruction, also received advanced paramilitary training. Probatier officers recently graduated by the Hoc Viên Police Academy or the Da Lat Military Academy had to undergo a complete instruction cycle on combat tactics at the ARVN Thu Duc Infantry School for officers, whilst patrolmen who had completed their basic training at Rach Dua also attended a similar program at the ARVN Combat Training Centre and NCO School co-located at Da Lat. At this stage, all combat training was carried out at squad- and platoon-level, which allowed the recruits to attend a good tactical manoeuver capacity in the field. Following this, the would-be Field Policemen – including officers and NCOs – underwent further eight weeks’ of training in CSDC paramilitary skills at the National Police Training Centers of Mã Lai Á and Phi Luât Tân. Instruction covered subjects such as jungle warfare, intelligence-gathering operations, law-enforcement and riot control techniques. To upgrade their capabilities, squads and platoons were returned periodically to these training centers for six weeks of unit refresher training, but for most CSDC companies and battalions posted in the provinces their refresher course actually took place at the regional training centers. Additional military "on the job" training was provided to Field Police units in the field by US Mobile Training Teams or by Australian advisors from the Australian Army Training Team Vietnam (AATTV). Selected officer students were also sent to the Royal Malaysian Police Field Force Special Training Centre (SLPPH) at Kentonmen, Malaysia to attend advanced specialized police and instructor's courses; after graduation, some of these new National Police officers upon returning to South Vietnam would them be posted as Field Police instructors at the Police training centres to pass on their skills to CSDC recruits.

Weapons and equipment
The CSDC was lightly armed by military standards, but heavily armed by conventional police standards. Its primary weapon was the M-16 assault rifle. In addition, each platoon had an M79 grenade launcher and a caliber .30 medium machine-gun. Twenty-four shotguns were available in the company weapons pool. The Field Police had no crew-served weapon systems such as mortars or any other indirect fire weapons.

Uniforms and insignia
Field Police personnel were initially given the same standard ARVN olive green fatigues as the other National Police branches, but from 1967 they began to receive a new ‘Leopard’ camouflage fatigues, dubbed the ‘earthen-colour flower’ (Vietnamese: Hoa Mâu Dât) uniform by the Vietnamese. This was a locally-produced copy of the American-designed Mitchell ‘Clouds’ camouflage pattern, which incorporated overlapping dark brown, russet, beige, light brown and ochre cloud-shaped blotches on a tan background.

Olive green US M-1951 Field Jackets or locally-made copies in camouflage cloth were issued to Field Police companies operating in the chilly mountain enviroment of the Central Highlands.

Headgear
Field Police troopers were distinguished from the rest of the National Police by a black beret made of a single piece of wool attached to a black leather rim-band provided with two tightening-straps at the back. Interestingly, berets were often carefully molded to achieve a pointed shape or ‘Cockscomb crest’, affected by so many South Vietnamese military personnel since it reportedly gave the wearer a more imposing figure and aggressive ‘Choc’ or 'Commando' allure. It was worn French-style pulled to the left, with the National Police cap badge placed above the right eye. Originally intended to be worn with the regulation National Police dress uniform in formal occasions, the beret was sometimes seen in the field but it was often replaced by camouflage jungle hats and US M-1 model 1964 steel helmets, the latter worn with a matching ‘Clouds’ camouflage cover.

Footwear
Black leather combat boots were provided by the Americans who issued both the early US Army M-1962 ‘McNamara’ model and the M-1967 model with ‘ripple’ pattern rubbler sole, standard issue in the ARVN. In the field, field policemen generally wore the higly-prized US Army ’Jungle boot’ and black or green canvas Vietnamese-produced Bata tropical boots, replaced by leather or commercial plastic and rubber sandals while in garrison. Some individuals had zippers put into the insides of their Jungle boots so that they could be laced permanently in a fancy 'airborne' pattern, while the wearer could get into and out of his boots quickly and easily by using the zipper.

Insignia
Regarding the placement of insignia, the CSDC had a system of its own, originally adapted from their dress uniform. Most CSDC troopers wore no insignia on their field camouflage uniforms while on operations, or sometimes just their Company patch in either cloth or metal versions in a pocket hanger following the French model suspended from the right shirt pocket.
