The "V" is really called the "combat distinguishing device," which indicates on certain awards that can be earned either during combat operations or non-combat activities, e.g., the Bronze Star, Commendation Medal or Achievement Medal, that is was related to combat operations. The award states specifically whether the combat distinguishing device can be worn or not. I suspect that Patraeus won his Bronze star with a "V" during the Gulf War. The Daily Kos doesn't know what it is talking about. They are trying to make Patraeus into Boorda who was wearing the "V" device improperly, i.e., it wasn't authorized.
Kos is saying he received it with the 101st in 2003-2004. If he has received the V device for a mortar round that struck near him, then it's a slap in the face to all of those who have been through lots more and have shown a lot more valor.
That can't be, if we believe Lovebloggers (post 132). According to that chronology, Maj. Petraeus (as he was then) was stationed in Washington during the Gulf War (Jan. - Feb. 1991).
