I don't think so. My experience in Viet Nam we only had the M151 series Jeep. There was the initial M151 then the M151A1 and eventually the M151A2. I maintained this series of Jeep until the active Army decided to go to the current 991 series HUMMV. I do miss the jeep, even after 20 years of being retired!

The film "Jabob's Ladder" is about the US Army, not the Australian Army.
Thompsons saw very limited use in Vietnam, and were mostly carried by forces which weren't American - the US Army used the M3 'grease gun'. The Navy and many second line units did use them, though, as did non-US forces in the region. They used them with 30 round detachable box magazines.
It was used as a defoilant to deny cover and concealment to the NVA/VC.
Most likely the US Army.
During the Vietnam war , the U.S.a used the draft system, that is you could be drafted into the army, navy or air force.
The Jeep was invented in 1941 for the U.S. Military by The American Bantam car company. The final production was awarded to Willys as the military felt Bantam was too small a company to produce the necessary numbers needed. Ford also built the Jeep for the military using the Willys plans. Bantam, which was the inventor, produced only trailers for the Army and never made the Jeep. Willys called their Jeep the Model MB and Ford called theirs the Model GPW. Jeep was never a name the military used. It was only a nickname in the beginning.
Kaiser Willys Auto Supply is the biggest supplier of genuine Willys parts, for a range of models from 1941 to 1971. VintageJeepParts.com is another source for genuine parts. There are also dealers who sell reproduction Willys parts.
All WWII jeeps looked like somewhat smaller CJs. The design was from the Willys Automobile Company, in response to a request from the Army for a 1/4 ton, four wheel drive truck. The Willys design was phenomenal, and the Army knew it wanted all it could get. Willys was a small company, and the Army did not believe they could produce the vehicle in the numbers wanted. The Army got GM and Ford to produce the vehicles (Ford-built models have the Ford "F" on every bolt head). As a sop, Willys was allowed to produce little trailers designed to be towed behind the jeeps. Willys did not long survive after the war and was bought by American Motors, who continued to build Jeeps for decades. Many WWII soldiers referred to the vehicle as a "peep", not a jeep (just like they didn't really call themselves "GIs" either - both are postwar revisions of what was actually usually said).

I think the hum V Jeep used by the army is the best off road jeep
M1911A1
It was invented in the war, so they could get around easily without using too many parts. JEEP Stands for Just Enough Essential Parts. The Jeep was originally a U.S. Military vehicle first produced in 1941 by Willys. It was invented to provide a vehicle that was 4 wheel drive, small, lightweight, simple, easy to repair, that could be used by the military to move troops quickly. The name Jeep, according to the U.S. Army does not mean Just Enough Essential Parts as the above answer says. That is absurd and 100% wrong. The word Jeep just means a small transport vehicle. It is even used by the Navy to describe small escort carriers, and the Army Air Corp Link Trainer. JEEP is an adaption of the letters GP, standing for General Purpose, vehicle.
During WW2 the British used the American made Jeep and called it Peep. They already had a larger vehicle they called Jeep.
US Army helicopters landed in South Vietnam in 1956. They were used in the Korean War in 1950-53.
The seventeen digit VIN was not used until 1981. The serial number is all there is on a 1958.
