This cannon-shaped USB hub features three ports that trigger an artillery sound effect when a device is plugged in. There is even a bomber for air support. Unfortunately, I would hesitate to bring these into battle.

The problem is, the canon and the aeroplane are both severely underpowered—they only support USB 1.1. These hubs are relics to be perfectly honest. I mean, you wouldn't go to Gettysburg looking for artillery to fight WWIII right? [Cannon and Airplane via GeekAlerts and Geeky Gadgets]
