Cadillac Gage Commando M706

 U.S.A. (1963)
Armoured Car – about 9000 built all combined V-100, 150 & 200.

Development of the M706

Terra-Space division of the Cadillac Gage company designed in 1960 4×4 amphibious armoured vehicle, expecting to fulfill the future needs of the army. The later required some sort of Jack-of-all-trades, a multi-purpose, 11-man APC, reconnaissance vehicle, convoy escort, command, patrol and a riot vehicle. By 1962, the patent was filed, and the projected vehicle named Commando. Development was fast as in 1963, the prototype undergone its first tests. The same year, the definitive production vehicle, the V-100, was tested thoroughly in Vietnam before the production was started in 1964. Total production figures are ellusive but at least 10 000 vehicles of the V-100, 150 and V-200 variants were delivered by CGC, then the Textron Marine & Land Systems company. The M706 is currently replaced by the M1117 since 1999, but still in service in many countries. Philippines are one of the most prolific user of the model.

To kept the prices low, the vehicle used many existing components. The axles were similar to the M34 truck series while the engine was the same V8 Chrysler, 360-cubic-inch gasoline that powered the M113 armoured carriers. It had a 5-speed manual transmission. These allows a top speed of 62 mph (100 kph) over rough terrain. Its 4×4 independent sprung roadwheels had massive tires to reduce ground pressure. The CGC can also swim at 3 mph (4.8 kph). Protection was provided by the “Cadalaloy”, a custom 0.25 in hardness alloy steel, protecting against small arms fire (7.62 cal.). This protection was also given by the well-sloped monocoque welded hull, also protecting the crew from mine blasts. However the alloy was not espcially light, and the empty weight of the vehicle was 7 tons.

This take its toll on the rear axle, which frequently failed, and not designed to support this extra load. Access was allowed from the two side doors, and the turret cupola hatch. Vision was provided by height vision blocks (at first ten) with armoured glass, and the revolving turret which featured a peripherical vision with ten vision blocks, plus a periscope. For close-fire, six pistol ports were also provided on the upper sides. The hull featured also an internal modular arrangement with interchangeable components, aimed at the export market.

The CGC accepted a large array of weapons. The first military version V-100 was usually armed with the same revolving turret that equipped the M113, armed with a twin M37 browning cal.30 (7.62 mm). This was in standard, but some versions received an upper open supertructure and one to three Browning cal.50 (12.7 mm), the front one being protected by an armoured shield. Later on, the revolving turret was equipped with smoke dischargers and a M2 cal.50. Additional supports were sometimes welded for extra M60s. An export version accepted a M134 7.62mm Minigun. The V150 and V200 were more heavily armed and better used for recce and support. According to the Wall Street Journal in 1965, the base price tag for the M706 Commando was 24.500 $.

The V100

This was the main, early production version. Apart the facts given above, there were two basic versions, a turret one, and an open-top version, with added upper protections. The side door, at first, in single piece, was later produced in two-parts. In 1964, one of the XM 706 prototypes tested a 20 mm armed turret, which never made it before the reinforced and longer V-150. The vehicle impressed the ARVN (Allied south Vietnamese Army which became the first customer of the V-100, apart the ATAC (US Army Tank & Automotive Command).

A 40 mm automatic grenade launcher and new turrets were also quickly developed since the AVRN complained about the lack of firepower of the twin cal.30. But the project failed to meet the US Army requirement and failed to materialized after US troops disengaged from VN in 1972-73. The USAF received the XM706E2, wiyh an open-top center parapet with with a single M2HB machine gun under mask assisted by a M60 or two. Some were still in service at Clark AFB in the Republic of the Philippines in 1988. In patrols, a crew of 12 was often seen, but it was systematic in ARVN forces.

The V200

The development was assumed by the Marine and Land Division of the Textron company. It was an elongated V-100 (in the middle section), partly based on U.S. Army’s 5 ton trucks components. It was built solely for export for the needs of the Singaporean army, or Singapore Armed Forces (SAF). Tey were modernized by ST Kinetics in the early 2000s and are still in service. Today singapore has 250 of these in service, plus 30 V-100 and 50 V-150.

The V150

This vehicle was based partly on the V-100, and the V-200. This hybrid was shorter but stronger and could accomodate much heavier turrets and armaments, and could be equipped with diesel or gasoline engines. Built for export, it was equipped with a large variety of armament configurations, including 12.7 mm and 20 mm armed turrets. Portugal had its V-150s modernized in the 1970s as the Chaimite, with a 90 mm Cockerill gun turret, known as the V-400 variant.

2,968 LAV-150 vehicles were produced. The list of operators includes Bolivia (10), Bostwana (36), Cameroon (43), CHAD (9), Dom. Republic (8), Gabon (9), Guatemala (7), Haiti (6), Indonesia (200), Jamaica (13), Kuwait (20), Malaysia (184), Mexico (28), Philippines (165), Qatar (8), Saudi Arabia (1100), Singapore (280), Somalia (10), Sudan (100), Taiwan (300), Thailand (162), Turkey (125), USA (10), Venezuela (130), Vietnam (5).

Other Variants

The LAV-300 is a 6×6 version, partly based on the V-150.
The LAV-600 is developed from the LAV-300 with much heavier weapons, the most common being the 105 mm.
By 2013 Textron unveiled the Commando Select 90 mm Direct Fire, a new model aimed at export-market, armed with a CMI Defence Cockerill CSE 90LP weapons system and asked to perform a large range of misssions from conventional combat to counter-insurgency operations.

Active Service

The characteristic sloped hull of the CGC quckly earned the nicname “duck” or “the V” in Vietnam, which was its first active assignation. CGCs were massively deployed there, as available, for patrolling the DMZs and acting as military police vehicle, guarding AFBs (Air Force vehicles), and for other tasks. These were hard-pressed, especially at the time of the Têt offensive in 1969 when Viet-Minh commandos attacked several key points in Saigon and many other important cities. ARVN forces also actively used their vehicles after US troops disengaged from Vietnam in 1972-73.

Many were captured by the NVA. After Vietnam, these vehicles saw limited use, and were affected to specific areas, like the Herlong Army Depot in California, and spent as targets. Other armies held their vehicles in service for longer periods, especially the Philippines. Many are still in operations. Outside these regular armies (Royal Thai Army, Republic of China Military Police, the Philippine Army, Marine Corps & Special Police Action Force, the Lebanese Armed Forces, the Army of Venezuela and the Jamaican Defence Force.), these vehicles has been used by many other operators for crowd control and anti-riot operations. SWAT teams also used some, as well as the LAPD. Later in 1991 gulf war, Saudi Arabia\’s guards V-150S took part in the battle of Khafji against Iraki forces.
