How to transport troops from surface to orbit?

There is an upper limit on how fast you can do this, but yes, with minimal handwavium, you might be able to do it. How do we do it? If you're allowing science fiction, let's handwave a nuclear fusion ...

How to transport troops from surface to orbit?

Assuming troops in orbit can survive and be useful you are talking about a rather high tech, well above what we have now. Are you sure you want them in orbit, not to get them to some other world? It ...
