by defalt the "3d map" is on. it simply consists of all the icons you see on the screen such as the icons for where the flags and silos are and the icon for where the titans are. it also shows green tags you see above your squad members and those red squares above the enemys that your squad spots. i sugest you leave it on unles your one of those realism freeks. lol i knew this one guy that even turned off the crosshairs in BF2 to get more "realism" but considering that BF214 is all about the future i wouldnt worry much about realism.
