Iron With Friends

Today's challenges are all really easy, with only Iron With Friends requiring some coordination.  Should only take 10-15 minutes to sprint through Winter Contingency, but does require co-op mode.  As usual, I'll be available at 10pm PT to bring parties into Campaign together to knock this out.  If there's more than 4 people on, join my party and I'll help folks coordinate before breaking into smaller teams.  Because today's challenge is shorter, if you are on-line by 10pm, I'll wait until 10:10pm to launch games if people are busy in matchmaking.
