Hi miked
yea the blocker is to prevent an attack. You can move in ncm into that SZ, if it’s been cleared but any occupied SZs can’t be moved into.
So your main Fleet can’t defend against your opponent’s Fleet, you put a blocker preventing him from attacking your Fleet.
He sinks your blocker but can’t move into your main Fleet SZ.
Hopefully you can reinforce to withstand a future attack or withdraw and block again until you can fight on at least equal terms.
