Other nations have mentioned the use of ironclads, and as for the steam tanks, the US Army experimented with them. As often as we consider steam power the realm of ships and trains, for a time, it isn't nearly as impractical as we tend to think. Multiple early cars were steam-powered, and of course there's the Army experiments I mentioned. In fact, there was a modern steam car that reached 140 or so mp/h, but it used propane and not coal, because coal is a really terrible power source. Also it looks like an SR-71.

Just for reference:

It's worth noting that the tracked one used steam because it had a flamethrower on it, because everyone in 1918 was presumably a massive fan of steampunk.
