CJ3B-J4 Military Jeeps
in Vietnam

Jeeps Active in Vietnam
The photographs seen here show CJ-3B-type Jeeps in use in joint U.S. and ARVN military operations during the Vietnam war. Many of them are CJ3B-J4 and J4C models, manufactured under licence in Japan during the 1960s by Mitsubishi, as well as M606 Jeeps built in the U.S. by Kaiser.

Mitsubishi J4C Jeeps
This 1963 photo shows U.S. military advisors with six ARVN CJ3B-J4C Jeeps.

Most of the Mitsubishi Jeeps are in ARVN markings, although the J4 and J4C were also used by the U.S. Army. These Jeeps appear primarily in support rather than combat roles.

Willys station wagons make an appearance in one photo, playing a role in a 1965 roadblock operation involving the U.S. 101st Airborne Division.

Willys roadblock
The Jeep in the foreground of this photo, taken at the Deo Mang Pass on 26 August 1965, is a Mitsubishi CJ3B-J4C.

For more photos and specifications of the Mitsubishi J4 and J4C, see CJ3B-J4 Military Jeeps on CJ3B.info.

There are several variations of the CJ3B-J4 and J4C models. The Japanese Army used a J4M which mounted a 106mm recoilless rifle,

the U.S. Army had an ambulance version, and there have also been versions with body armor added.

The U.S. Army issued an "Armor Adaptation Kit" for the Mitsubishi Jeeps, consisting of steel plates for windshield, sides and back. There are photos in the installation manual for the kit (see Armored M606 Jeeps on CJ3B.info), but no photographs have surfaced showing it in use. The kit appears somewhat primitive in comparison to the armor in the photo below.

This Mitsubishi J4C with a locally-made armored windshield, was photographed in Saigon on 13 September 1964, being used in the suppression of the coup d'etat by Lt.General Ngnyen Khanh.

Armoured windshield
In the background of this 1964 photo of an armored J4C, are several other Mitsubishi Jeeps.

The Ford M151A was the principal U.S. combat jeep in Vietnam, but the Kaiser-Willys M38A1 is also in evidence in the photos. Although a newer design than the CJ-3B, most of the M38A1s had been in service longer than the CJ3B-J4C's made by Mitsubishi.

This photo of a convoy crossing a bridge, taken on 18 March 1965, shows a U.S. M38A1 followed by an ARVN J4C and M38A1.
