So it seems to depend on what your squad does because I’ve been purposely playing support and joining squads with no medic. The result, no stat for revives listed. Even though one match I had 9+ revives as support player (I can’t help trying to beat the odds when a squad mate is down). Still no revive stat. Then played rounds as a medic and made sure I was in a squad with another active medic. Revive stat displayed.
