Differences between NROTC and AFROTC summer training setup

From reading on their websites, I get the impression that NROTC and AFROTC are set up differently with summer training and opportunities.

What is NROTC's equivalent to summer field training? When or does it take place? Whats the deal with marine option cadets having to go to Marine OCS after ROTC? Is it the same for navy?

Does AFROTC have opportunities after field training similar to the summer cruises/carreer exploration?

If possible, could someone give me a grid of everything a AFROTC...
