Ok in there specific role as mobile nuclear launchers I'm sure they'd be functional, but they cost billions of Dollars and you really could just strap a nuke on most other things.
Any kind of military armor is a really big target to everything on the field. Most metal gears are extremely tall, you might as well paint a large bright neon target on it for all of the enemies own armor and Air Force.
Not to mention they are moving on 2 very mechanically complex legs. Have a squad of tanks/helicopters/jets/long range missiles/squad of anti tank infantry focus on a knee joint, even if you can't kill the whole unit quickly you can drop it to the ground nullifying most of its attack capabilities.
realistically the tech needed to make this stuff possible doesn't exist.
It's as Solidus said, it's more of a liability than an advantage in almost any circumstance.
AI and Nano Machines made for a much better plot device (its why I consider MGS2 the best)
