Reminds me of the Moron ai's I used to find when playing Scorched Earth, put just enough power into the shot to roll the shell out of the cannon barrel. You really only had to worry about one of them killing you if you started the round right next to one.

You know what happens when you break the stick off a bottle-rocket and light it?

Yeah I bet that happens sometimes here too. That's why tank cannon barrels are rifled if they aren't firing fin-stabilized munitions. I'm sure this video is selectively edited to give the impression of accuracy.

So that's what the hell a Gauss cannon in Halo is.

You're right mate, best bang for your resale buck if you wanted to net cash outta this romp would be the highest-end electronics still in the box on an auction site-I'd focus all my speed-seconds on Nikon, Cannon, and Leica! Practice the cube-stack and scoot that sucker to the bin on the floor just in time!

Your title is better though, I must say.

He's keeping his cobra assault cannon off camera..

At a recent gun amnesty (which is similar to these gun buybacks) in sweden someone turned in an anti aircraft cannon.

And for the record that AT-4 is not an RPG it's technically a recoilless grenade launcher
