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...
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...
