Cable has a special attack power

Tactical Movement: Once per turn, for all characters with this power, Telekinesis as FREE.

At 100 points, Cable can have 2 additional clones with the same starting powers. I'm trying to understand how his TK works. It appears that he does not have TK to use as a power action, but it can be used once per turn as a free action, but only one of the three figures can actually use it each turn. So each turn, I can pick one, and only one, figure to use TK as a free action. Then the next turn I can repeat the process again.

Is this correct?

That’s correct

Don't forget that they could TK themselves. Only one per turn but helpful to get into or out of range
