Well... firstly, I'll get a truck or bus, pick up survivors on the way to the middle of the city. There, I'll raid the Hunting Shops and then get to the harbour, where we'll set sail as fast as possible, and stay on deep waters, untill there ain't more survives comming out of the city. On the way to the harbour will get as many people to follow us, and we'll launch an armada of ships. And get some of the Danish Naval ships for protection.
After that, we'll start making batteplans, and begin to raid along the coast, and try and take the military bases. I think Bornholm would be a good place to clean out first, since it's an island, and the Dansih Stormtroopers are stationed there.
From there, we'll begin to take our country back, one by one.
I recommend Sweden and Finland follow the example, and go for Bornholm as a base of operation.
