I'm not even sure who is making the Abrams these days. Heavy armor was not an area of interest for me. They looked pretty new to me. All the older ones are all desert tan, at least for the last 20 years. The treads on the tracks looked new, but theoretically they could have been retracked. They can only load one M-1 into a C-17, so flying them would be pretty silly. They would have to get loaded onto a Roll-on-Roll-off ship (Ro-Ro). But i dont remember them having them up there. Its been nearly 20 years since I was at the Everett base, so it could be. I'm pretty curious though. Thats a lot of firepower
