Any info on Kalamazoo K45/K60 series vehicle being used by U.S. Military?

Ok was at a car show with the M274A4 Mule and someone came up to me and asked if I might be interested in what he called a Kalamazoo vehicle that he got from an Air Force base.
I did a bunch of searching but basically found no matches until I searched for Kalamazoo Manufacturing Company, then I found this http://www.kalamazoomanufacturingco.net/trucks4.htm

I can see where the vehicle could be used for military support as depending on which vehicle specified can carry either 4,000lb or 6,000lb loads, and the one I actually like the good old reliable Chrysler 225 Slant 6 engine.

Does anyone have actual pictures or info on if it was actually used by the military?

From Wikipedia- Meanwhile, the company continued to build Speed Truck products. The model K45 was the largest platform truck in their 1960s catalogs with a 3,000-pound payload.

Thats all It says. I was kindof hoping it was actually a railroad cart, as Kalamazoo built those first and for many years.

Did some more research and while it isn't one of the Kalamazoo made vehicles it is from the company that now makes the same type vehicle. Basic same vehicle different engine. It was used in the Navy and I'm going to look at the one for sale locally just to see it.

Turned out to be just like the above vehicle, probably one of the ones toward the end of Kalamazoo manufacturing companies life. It has the Ford 2.3L OHC engine in it with a carb. and distributorless Ignition. It was in decent shape but just not my cup of tea.
