In scrolling through the list of U.S. military M-number vehicles, it looks like the Army trialed a large number of 8x8 cargo trucks in the 1950s until the Vietnam War or so. They vary in cargo rating, from 2 1/2 to 10 or so tons, not including oddities like heavy tractors, and some appear to have been developed for some kind of amphibious program? information is rather scarce, but it seems like the only one to enter service was Ford's M656, used by Pershing I missile units. So i'm curious if anyone has anymore information about these or knows what program they belonged to? The ones i've found are:

XM410 and XM410E1, Truck, 2.5 ton, Chrysler -Amphibious truck, View: https://youtu.be/e6B5ezE9WNs, Torqueflite automatic transmission, 361 V8

XM409 Truck, 10-ton, International Harvester

XM357/401 Truck, 4-ton, FWD -One of FWD's Terracruzers with low-pressure rolligon wheels. FWD Model 8-320B were bought by the Navy and Air Force, with the latter using the MM-1 designation for it when used as a specialist missile hauler.

XM453 Truck, 5-ton, GMC-Ford-REO -amphibious

Intreging RipSteakface, I was oblivious to such capable U.S. designs.
I've always found it odd that the US Army seemingly neglected true cross-country trucks, when compared to the awesome designed and capabilities of the Soviet/Russian Army.
I appreciate that roads and the environmental conditions in the Soviet Union/Russia are auster/rudimentary when compared to the U.S./Western Europe, but still......

I have several books which feature large numbers of US go anywhere truck designs from the 50s through to the 80s
But it is amusing to note that the old fashioned looking design won in the end.

Dear friends,

I am looking for any kind of information and pictures on the testing of MAN 8x8 truck that took place from 1978 to 1979 at Aberdeen Proving Ground. There were 2 vehicles, identical to the German Army „10 t gl“ trucks, long wheelbase with rigid platform tested there.

Attention: I don’t talk about the later MAN 27.365 VFAEG vehicles that were uses for PII and GLCM, that are recognizable with a shorter MAN cab and a cooler mesh on the vehicle’s front.

After the testing of the „real German-spec“-trucks, the HEMTT was tendered separately (ending up with the Oshkosh) and the above mentioned MAN 27.365 VFAEG were ordered directly.

I was told that these two test trucks still survive today.

Unfortunately, any efforts to find any expert in the US, was not (yet) successful.

Comments, info or even private emails are much appreciated.
