Humvees and Flatbeds in somalia

The version of 5 ton truck I think was the M925 and the humvees were the normal hatch back version

I'm not sure what the exact model/version was. It's possible that there were a couple different versions out there. Most of the stories you read, they don't include the model number.

From the above, take a look at this and it should help to narrow it down.

According to Mark Bowden's book "Black Hawk Down", the vehicles are referred to as wide bodied Humvees and 5 ton trucks. Hope this helps.
