nothing personal TrackerBen but Battleship is garbage, that you mentioned tactics in the same context as a bag of popcorn like that kinda makes me weep a little for humanity, the comfort I take from the comment is in the knowledge that it won't be long until you realize what you said.
No problem. I never said Battleship was a great movie, only that the last scene amazingly saw a WWII battlewagon perform an 18th century maneuver in order to take advantage of the aliens' dumb rules of engaement.
Otherwise a realistic naval engagement would have seen missile and counter-missile warfare overseen and managed by naval AWACS,with manned squadrons playing chicken and decoy runs around the aliens' sensor horizon. It would have been Sea and airspace contest centered on carrier strike groups, with Aegis ships and attack subs dashing down approach channels swept by ASW and CAP, launching wave after massed wave of SLBMs and ALCMs and Harpoons distributed and timed to arrive from most points of the compass, perhaps with a few land-based ICBMs thrown in to stretch the aliens' defenses. But this would be boring cinematically.
