MOOOOOOOOOOOLTO INTERESSANTE .
It would seem that not many players know about this, but here is what it says in the patch notes:
Please note! When Update 0.7.5 hits the live servers, all players will have a chance to complete the following combat mission: Play one battle of any type with Tier VI cruiser Pensacola to get 190,000 Elite Commander XP. This will allow you to easily redistribute the skill points of the Commander or retrain the Commander of the Tier VI Cleveland to the new ship. The combat mission will become available for completion until June 29. Please note, that this combat mission is not visible in the mission list!
In other words, get Pensacola and take her out for one round in co-op and you can get a ton of free captain xp.
Ostensibly, it's for retraining your USN cruiser captains, but I used some of it to retrain my 15-pt Iowa captain as well.
Deadline is June 29, so don't take too long!
