I thought there was something similar to this in here but I searched HA, harbor, and
misisons and didn't see it so here goes...

Since the devs are so fond of missions, I think would be good to have practice
harbor assault mission representing each harbor. For up to, lets say, 20 players.
This would let fleets practice HA tactics and give non-fleeted members a shot at the
assault mode. The harbors should be sufficiently fortified to present a challange
with a good mix of AA batteries, gun batteries, mines, and coastal guard ships.

In addtion to the four national harbors in game. I think the Pearl Harbor map could
be adapted for an HA practice mission. And of course, when thinking of amphibious
assaults, how can we not consider a D-Day mission to recreate the attack on
Normandy.
