Probably so, heading for the bone yard. They look like they're already partially stripped out.
Hard to tell from the pictures with the shadows, but according to my neighbor, Mr. Army Reserve, "They might be old M113 APC’s. If so, they've been around a long time. Came out during Vietnam and are still in service in some units. They had aluminum armor which would give them substantial scrap value."
If you really care!! Floats my boat. . . or not!!
