Wow, so I guess they were picturing everything reverting back to 19th-century warfare? Or maybe, they were picturing what actually happened, but they didn't know what to call the heavy, but still fast and maneuverable, gun platforms we now call "tanks".
I guess it goes to show that you have to consider what a new military technology adds, as well as what it subtracts.
Yeah, not quite an assault shed, but still pretty substantially covered, going by the picture.
The way you put it, I was expecting an unmodified tank capable of normal tank operations, in, like, a Western test.
