The most recent one I remember involved a fleet segment deciding to desert from an upcoming battle. A lot of time was spent deciding the weapons and tech suite load-outs and communications between captains (space ships naturally) and deciding who could be trusted to be let in on the plan. There was an acute tenseness owing to the fact that they would have to leave their families behind, but there was not much choice as they believed they would not have been able to do more than briefly delay the enemy. The big battle, or escape as it were, never happened, but the characters were remarkably clearly fleshed out when I woke up.
