A squad member and i were multi crewing in a tank on (the really big map with two bunkers in the middle) at grid Delta 4 i spotted an enemy APC visually but i noticed they were blue on my tactical map. Even a troop spawned out of the APC and had a blue name. It did not appear that way to my gunner so it just made me sound crazy
We killed them and got no negative score.
Also friendly radio chatter called out a enemy tank in D 4 which we could not spot. I started to think maybe they were talking about us. i could not confirmthis however so it remains speculation.
