Federation Commander

I have two questions about the Juggernaut and its' rotating shield. First, does scoring a hit on either of the shield boxes disable part of the shield?

Second, do you have to put power into the shield for it to work?

1) No. Both boxes must be disabled to disable the rotating shield.

2) One point of power charges 10 shield boxes. It would take 10 points of power to activate all 100 points of shield boxes. This is written directly on the Juggernaut ship card ...
