What’s it like being in the Korean military?

I’m not Korean, just an avid Kdrama watcher like the rest of the western world. I just watched D.P and then Military Prosecutor Doberman and I’m fascinated by it all, so I wanted to get a more realistic first hand account of military life here.

Please share your stories if you care to. Additional questions I have include:

For those who have been, would you say it has shaped you in any way, be it positive or negative? Has it instilled discipline and/or strength into your mind? Has it traumatized you?

Thank you.
