Retraining
You can retrain your crew for a different vehicle, or simply boost their current level. Once a crew member has been recruited, his nationality and role will be locked in, and will not be changeable when retraining. A crew member can also increase his skill in the vehicle he is currently in, as long as the vehicle selected for training is his own.
Just like training, when retraining, you will have three levels to choose from. Retraining a crew member can be done by opening the crew member's profile and selecting the "Training" tab.

At the cost of 20,000 credits, this option retrains a crew member to 75%. If a crew member's primary specialization is below 75%, then his primary specialization after retraining is automatically 75%. If the crew member is above 75% in primary specialization, then after retraining it will be as follows:
If the crew member is retraining to a vehicle of the same class, then the final experience is 90% of the crew member's current experience level.
If the crew member is retraining to a vehicle of a different class, then the final experience is 80% of the crew member's current experience level.

This option is free, and retrains a crew member to 50% in primary specialization, which is the absolute minimum that a crew member can be. The final primary specialization level after retraining through rapid courses is as follows:

If the crew member is retraining to a vehicle of a different class, then the final experience is 60% of the crew member's current experience level
