Okay, has anybody ever heard of ARMOR 4-64? I think it's 2 guys and a tank. Anyway, here's a mistake they made: They took a Pirate Flag with Crossed Swords instead of bones, and they put it on their tank.

The reason this is a mistake is because to the Human Eye, the pirate flag distincly symbolizes Hostility. So it's kind of like walking into a public school with an gun in your hand in the nude, it's not really a good idea.

The reason I think this is because I'm a history major and I have heard of events where trade ships were attacked by the crews of ships with Jolly Rogers on their poles (A Jolly Roger is a Pirate Flag.)

They are referinng to the 4th Battalion, 64th Regiment, of the 3rd. It's a military unit, not a piece of equipment.
