How to remove lock on tanks?

I have several locked tanks that are just wasting space. How do I remove the lock?

From the army screen, tap any unit to go to the unit selection screen.
Tap the lock in the lower right corner, it should begin to blink.
You can now lock/unlock tank, tap the lock when you’re done to save the changes.
