[Metal Gear] What makes the Metal Gears/Shagohod/Sahelanthropus so special?

I mean... tanks on legs? And some of them can launch nukes? What's the fuss all about?

In that reality nukes were disarmed fairly early on in the Cold War, so having a giant walking robot scaring armies and firing tactical nuclear weapons is kind of a big deal.

Plus metal gears are (supposed to be) nearly unstoppable to normal forces, and require special operation units to take down.
