I drove the M60A3 Patton tank in the U.S. Army, thus the name "TANK GUY". Originally it was going to be "KNGTYGR", or "PZKWVIB" Because my favorite WWII tank is the King Tiger (Panzerkampfwagen VI B).
But I thought tank guy would be easier for everyone to understand. How wrong I was! People think I remove oil tanks for a living! LOL
Here's a picture of my M60A3 Patton MBT - TTS (Main Battle Tank - Tank Thermal Sight) on the Czech border in 1984.
