Help me unlock the mystery of my ex army truck

[fredscarryall]

I pulled my truck in the garage today. I found out the entire truck was painted drab green. Then someone painted it dark blue with a roller over the top of the green. Then I saw some numbers or letters on two of the fender so far. There in not a lot of info on the net. Does anyone have info, pictures or can shed some light on this truck. I don't see a star on the door or hood. But about half the truck is covered in blue.
