My character is Resaz. An Itani character currently in the Itani Military. Today, I attempted to join in a small skirmish, and then a large skirmish. Both times, I received this message.

"You don't meet the requirements for the ___ skirmish mission. You are in the serco_military! You are not in the itani_military."

Behead the traitor!

sounds like you just may have joined the Serco military... welcome to the winning team.

I fixed this a few hours ago. Thanks for the report :)
