A TV news reporter who specialized in the military and Exofleet. McKenna accompanied the Exofleet on their campaign against the Pirate Clans of Saturn and attempted to interview Kaz Takagi concerning his actions aboard the transport Danube. Thankfully Marsh stepped in and declared that "That trooper acted correctly under the circumstances, and I take full responsibility for the troopers under my command." After that, McKenna was only seen once more. And that was aboard the bridge of the Resolute, shortly before Winfield had him thrown in the brig.
