Hey Batbomb,
Nauru is a nice add. It was the original target for Operation Kourbash , the Army partner for the USMC 2nd Division's
Operation Galvanic (Assault on Tarawa) in Nov 1943. The assault on it (Nauru) was switched to Makin Island when the planners decided the defences were too heavy on Nauru , and its geographical structure ( basically a gradual shallow hill stationed with artillery that could cover the perimeter due to the elevation difference ( Morison likens it to a hat with a brim , the airfield being on the brim and the guns being situated on the dome.
I had hoped that someone would apply all the northern Gilbert Islands on one large map , and then cheat the geography (between Nauru and Makin/Tarawa) to just include Nauru on the western edge. This would be excellent for online campaign purposes (I know , not the Mandate of SAS - it doesn't mean SAS folks wouldn't appreciate it).
The Tarawa map always bugged me because it implies that Tarawa was an isolated atoll , which was not entirely the case.
Cheers,
