I see, thanks. Well, lots of things could explain this. Shipping new equipment from the factory to a military installation.... a battalion moving somewhere for reasons known only to them.... war games .... surplus equipment being moved to ship to foreign allies.... or actual combat expected somewhere. I grew up in a rural east Tennessee town and the railroad that went through the town often had long trains of these tank and truck shipments. So it's not new, I guess we just don't seen them this much anymore. But there are quite a number of reasons this could be happening.
