You mean, what do You get for them, or literally what does each one indicate?
I would be nice to if you could keep track of your medals like most cod games. Especially, in a ww2 based game. j/s
Somewhere, I have seen the medal count after playing War. Maybe the stats summary or progression section. I play for fun so I don't dig around the game and get too deep
Go to soldier, then dossier, then challenges. There you will see how many medals you have collected towards each challenge.
you can look in the after action report, progression i think to see the medals earned, and what you receive for each
