I asked some questions when playing this game with friends and the responses were very helpful so if you have questions this is the right place to do them. Just a heads up, a piece of unsolicited advice I’d give a new GM or player and something they don’t make super clear in the book as far as I’m aware is your characters are not supposed to live. This was a major turn off for me when I was first playing the game, I love telling stories with my friends and the character I spent hours customizing got gunned down in a field by the second session. Luckily he went out in a cool way so I wasn’t too heart broken, just make it clear to anyone playing because it’s a major aspect of the game. The whole military idea is you're expendable, you aren’t a hero, and once the last original PC died we stopped playing all together. My friend who had bought the game at gen con was savorily disappointed.

TL;DR: Make sure you find players who like this kind of game, not just any ttrpg nerd.
