Yes, they are correct. I've done extensive searches on BMY/Harsco (aren't ya proud of me DH??) and they ONLY cater to the military with these trucks.
This is where the common sense is going to have to come into play.
I can title an AMG, Jeep, International etc., military truck 800series with no problem since they make non-military stuff too.
The 900 series is a more "civilianized" truck with better safety features etc., so the GA DMV is just gonna have to bend a little and use that common sense approach and make another category or simply title/register these trucks in the "other" category!!
We'll just have to see how much hades has to be raised to get there!
