You could try comparing it against the Betito scenario at #49, and map #29, while you are at it.
Looking now
Scenario #49 and Map #29 are basically around the northern end of the island, and you come in mainly after the battleships have pounded the island and inflicted casualties on the defenders.
Baseman's scenario is more of a full (as close as you can get within SPCAMO games) representation of the island, you have the southern half as well, and starts when the battleship bombardment is underway (go USS Maryland!)
His scenario is a bit TOO big for me to handle; it's truly a giant scenario, hitting the 500 unit limit on both sides.
