Some map overviews for the Back to Karkand maps are here. Note that some of the pictures are from the console versions, and some are from the PC versions.
I'd post pictures but BF3blog sucks and makes them reroute to that i <3 bf3blog image.

Commo Rose was a much requested feature for Battlefield 3, but the version that managed to ship with the game is awkward and practically useless, as it’s missing key commands — the two most needed commands (“Need ammo”, “need medic”) are not there. Now according to DICE sound producer Tomas Danko, DICE have updated Commo Rose quite a lot, so much in fact, that they’re referring to it as “Commo Rose 2.0″. Danko recently Tweeted:
“We have patched and updated comrose big time, it will be distributed shortly.” “It’s so updated we refer to it as comrose 2.0. Soon in a patch near you. :D”Danko also confirmed that players will be able to request ammo and medic help with the 2.0 system. Commo Rose a communications interface used by holding down the “Q” button, where after a menu pops up where players can issue commands, request stuff, etc. No word on when the next patch will be released.
