In MW2, one of the Rangers (Dunn I think it was) said that special types of missions (as if they didnt do anything "special" total sarcasm) that it is up to Delta. "Those missions are for Delta". And MW3 in the Black Tuesday pre-game dialogue that you can see a glimpse that lasts 3 seconds of the 75th Rangers Regiment. You played as them in MW2. But Delta was JSOC. Or the team you lead in Black Ops 2. But thats a story for another day. But what the hell are the Rangers doing there? Did Overlord send them there as he is seen if you use subtitles. Well then thats all I have to say right now. Peace. Hope you enjoy.
