The Leopard 2 battle tank was developed for the West German army in the 70s and has a fully stabilized main gun. What does that mean? It means that even if you’re flying along at 30 mph on bumpy ground, your gun remains steadily pointed on-target (like an owl or chicken head). It also means you can balance a full mug of beer on the gun without spilling a drop, making the Leopard the world’s best and most expensive waiter. (via @MachinePix)
Update: Here’s a longer video featuring the same tank. The commentary is in German, but the visuals aren’t that difficult to follow.
In addition to covering how the stabilizing gun works, they show how the tank stays level over uneven terrain and how the gun can stay locked on a target even when the tank is moving from side to side…the video of which is unnerving. (via @le_barte)
