> but Marines, in particular, have a very tough time adapting to life and careers outside the military.

I'm curious why you have that impression. I spent 6 years in the Marine Corps Infantry and I've found it super helpful now 6 years into my career as a software developer. Specifically, because of the leadership style you learn.

The only thing I'd say it made it more difficult to adapt to was college where I had to interact with a bunch of kids with no life experience and lots of strong opinions about how the world does and should work.
