| This device works on a rather simple principle: turns out that all tanks ever made by any country have a javelin sized hole on the right side. No one says that because no one else knows, nobody ever thought to look. But I know. So, if you can score a clean hit with a spear, you can get past the mighty armor of a tank. |  |
| Now for the spear design itself. Take a spear, and get it really REALLY sharp. Then impale a tennis ball the the end. That will make it all bouncy, bouncing off the inside of the tank, hitting the guys inside, and leaving a really bad bruise. |  |
