M-76 Otter amphibious vehicle

Tracked amphibious carriers built by Pontiac in the 1950s and used during the height of the Cold War in places like Alaska and Vietnam as well. Prop driven in the water, road wheels are inflatable tires, not solid rubber. It was a pretty neat vehicle, primarily used in a supply or support role. Did pretty well with the rice paddies in Vietnam, but just about anything that was fired at it went through and through because the otter had a totally enclosed, insulated aluminum body. It had space for eight passengers plus the two-man crew, or 3,000 lbs of cargo. There were hatches in the roof, and a pair of doors on the back for loading and unloading passengers or cargo. The crew compartment had doors on each side.

I wonder if that's a gasoline tank on the side?

Added by Mark Holloway on 28 February 2011.
The tank is a gas tank.I worked on Otters while I was in Dong-Ha.The Otter platoon was stationed in Quang-Tri. The main purpose was for quick troop disbursement and taking supplies to Khe-San. When supplies were taken to Khe-San we had to provide a mechanic to go. All the Otters I seen in Nam were sandbagged very heavy on the inside and modifications were made sometimes with heavier metal for protection.

Main base was Quang Tri, forward was Cua Viet, located at tha mouth of the Cua Viet river on South China Sea. Resupply was where we were sent to .
How do I know , Sgt S. Morning USMC , I was there.

I was with the original group of 33 M-76 Otters sent to Danang Vietnam in 1965 by the Marine Corps. There were seven Marines trained as mechanics and instructor on the M-76 in Barstow, CA before being deployed. I was one of the seven - Sgt Barbosa (NCOIC), Cpl Bennett (me), Cpl Bolick, LCpl Blanchard, LCpl Bryant, LCpl Gordon and LCPl Brandon?? - not for sure on last. We were originally with 3rd Motors. Eventually, there were attachments of 3-4 otters detached to different grunt battalions from Chu Lai to Phu Bai. Every other Otter had a 50 cal mounted on the top with a 360 turret. The otters were used mainly for re-supply and did a great job at it. They could go almost any place - rice patties, swamps, water, etc - did not need roads. I left Vietnam in Aug 1966 and we had lost only one vehicle (of the original 33) to a rocket. I still carry a picture of an otter in my wallet that I took at the port in Danang when we off-loaded them from a ship.

We had 2 M-79 Otters in Combat Support Co 1st BG 23rd Inf Ft. Richardson Alaska back in 1962. They were great snow vehicles but very hard to start in sub zero temps, it used an air cooled opposed engine mounted vertically. It was light and it road on top of the snow (like a snow mobile)

The otters arrived in Chu Lai first 1965 I was there with C Company 3rd Motor Transport Battalion 1st Marine Division FLSG #1 1st Marine Brigade.

Added by Dennis Becker on 30 September 2015.

There was 33 otters that arrived aboard ship at Danang in Sept/Oct 1965. They were off loaded and taken to 3rd Motors just southwest of Danang. After the vehicles were serviced, ten of them were sent to Chu Lai. Corporal Bolick went with those otters. See my comments above. We also had one otter hit by a RPG (south of Marble Mountain) and it burned about a third of the vehicle. Have pictures of it. Great to hear from you and other Marines who were with the otters in Viet Nam. I know the otters did have an important mission there.

Added by Ray Bennett on 30 September 2015.
Operated one of the last Otters #176735 in late '68 & early '69. Was with 11th Motors Bravo Co, assigned to 5th Marines. They were phased out when the M116 Huskies finally arrived. Otter was a great rig to run -- never stuck it, never deadlined it, never dropped a track. Had to change the auto trans fluid regularly to keep it from "burning". No one ever asked to ride in the back with the fuel tanks staring you in the face, and no one wanted it parked nearby when we knocked off for the evening. The bilge pump never would keep up with the water coming in the tweaked rear doors, so river time was limited. But some good times were had by a lot of us.

MIKE, I WAS IN T CO IN 67@68 did you go up to Hue in Jan 68 if so, we were together over there!

I had 2 sections of otters at camp carroll from nov. 1966 to may 1967 got orders to pull back to phubi that's where I left the otters and men when I rotated back to the states for discharge.

Added by Sammy G.{ Fireball} Phillips on 28 February 2016.
To Jim Kleintop: Jim, I was only in Bravo Co, even though Otters were only assigned to "T". Got into a minor disagreement with the Bravo Company Gunny -- he packed me off to 1/5 An Hoa with 1/2 hour Otter training in the motor pool. Probably hoped I would never make it back. Got up to Hue numerous times on 5-ton convoys in 68, and switched back and forth from driving to Huskies in 69 until I came home. Maybe you remember John Kirkland and John Martel -- only two names I can recall from "T" Co Otters.

I would like to see the photo of the melted otter by a RPG. The melted otter was in our compound after operation starlight, the guards wouldn't let me take a picture of it. They said there were Marines inside the melted mess. But I remember the glob of metal could hardly tell it was an otter. At the time I was with C Company 3rd Motors in Chu Lai.

I was an otter instructor in Albany, Ga. Back in 1966. We were told the gas tanks were lined with some kind of rubber if hit would reseal it's self. In Nam I almost found out, a round just missed the fuel tank and went straight threw the rear compartment. ALSO, the otters were Army hand me downs. They had a star that was to be painted over and Marine Corps vehicle number to be added on front of vehicle not on doors. Marvin Lockard USMC Vietnam. 1967 1st & 11th motors.
