there's more and more accounts of this past weekend's game where gmr was off doing stupid shit that they weren't supposed to be doing, IE clearing buildings already cleared and known to be cleared outside the area of operation to make themselves look cool, and when asked to rejoin the rest of the force, the command staff were told to fuck off. In this case, it was Col McKnight they told basically to shove it.
Also from this game were accounts from players that none of the gmr players were calling hits when they breached rooms. Not calling something in the heat of a moment is one thing, to consistently do it game after game and have multiple players from all over the US say they're not calling hits is more than just coincidence.
Not to mention personal accounts of people here of gmr players being asshats at previous games.
I futz with V2s, V3s and V6s. I could be wrong... but probably, most likely not, as far as I know.
