*I know you have to do some friend or foe recognition but at least real WWII pilots didn't have to worry about what nationality planes their wingmen were flying that day.

I thought even in sim mode you get a coloured box around aircraft when they are close in every mode other than dogfight. You don't get a direction indicator when they are off screen or the distance to then, but enemy planes do have a red box around them when closer than 2km and in view. I could be wrong I've only ever found one sim team battle game since the game came out.
