Another pdf hit the online community, and this time its a pretty obvious one for Tau. There are just tons of vehicles and even a stolen valkyrie with Tau weaponry on it. I am not going to post a link directly to it. Here is where you can find this one if you are interested. Don't spend much time on it though, its obviously not real, but a fun read.
