This is either the coolest tank nerd thing I have ever seen or it is kind of sad:
The one thing that does annoy me is that he refers to it as a "Panzer Tank," which is wrong, or at least completely unnecessary. It's like saying a "Tank Tank" Or "Armored Vehicle Tank." But other than that, this is an act of geeky genius.
What worried me, though, is that when I did some research to find the right code to embed this video here, I discovered that there is an entire subculture of paintball-based tanks. Look what happens when you search for "Paintall" and "tank" on the video site Liveleak or Google "Paintball Tank."
