How long do Command card abilities last?

By lunitic501, in Rules

So for example Bossks 3 pip gives him sharpshooter and everytime an enemy unit activates he gains an aim token. So does he keep those abilities for the rest of the game or just that round? I have looked in the RRG and cant find anything on the topic.

End of the round, unless stated otherwise.
