I can't move my planes

[panzers]

I try and rebase or strategic move them an all I get are a series of blue x's and they don't move.
What am I doing wrong here because the rules don't clearly tell u what to do other than to just move them

Did you hit the rebase button ?

Once you hit the rebase button , the blue X will disappear then select a hex you wish to go

Manual reads
The rebase range is 40 hexes for Fighters and Tactical Bombers, and 80
hexes for Strategic Bombers. It also depends on the unit’s actual level.

I didn't know there was a rebase button. guess I have to look
