I think this would be even a sort of motivation to do more heroism in battles, put more effort in playing.
Tired of seeing “best trooper” rewards, or how to call it. Give us Medals, and ribbons for doing well in battles, destroying many tanks, medals for heroism and so on. Medals for defending point at your own and surviving, medals for helping comrades from downed state (yes you could do that).
Also I would love that i would can put ribbons on soldiers. And that would be nice customization of soldiers.
