Sabot haven't they in past years also had some older equipment running about? I've seen photos of a T-34 running around a road on one site that I thought was at Ft Knox at Fourth of July.

Looks like a great show. I'm going to have to look to see if Ft Carson is doing anything like this.

Yes, they moved the mock attack with vintage vehicles to Memorial Day and hold the 4th of July activities separately. I took photos of the vehicles at the Memorial Day displays and uploaded them here.
