User blog comment:Ferrariguy1000/First Blog! Unique Accessories for guns? Opinions on Close Quarters, Sorry if I'm a noob, but what is CommoRose?/@comment-3224196-20131204181212

The commo rose is operated by Q (default on PC) and R2 for PlayStation (BF4 only), but I don't know with the Xbox (BF4 only). It allows you to request support, and to respond and provide team support.
