[2019] French commander

Hey Chain_shot,

Yes, you can meet this requirement more than once in a match. You can find all the details about the new commander in the dedicated article: https://worldofwarships.com/en/news/game-updates/french-destroyers-part-2/

What do you mean by "is it permanent?"

All of these talents can be activated multiple times per battle.

Oh, no this is on a per match basis.
