The little golden up-arrow in the tank crew part of Garage UI

The second crew member has this little golden thing next to "91%". I didn't notice anything unusual on his card, nor anything to change or upgrade… I checked the guide and it wasn't mentioned. What am I missing?

Accelerated Crew Training Bonus Option: For Premium Vehicles and for fully researched Elite Status vehicles, the Player has the option of checking the Accelerate Crew Training box that appears above the crew panel in the garage.

The vehicle's experience at the end of each battle is then distributed among the crew members and the crew member with the lowest Training Level will get a double portion.

Accelerate Crew Training can be toggled on and off at any time via the check box, and each time a dialog box will appear to notify the player that it has now on or off
