Here's how I see it:

The episode(s) focusing on Guadalcanal will show a little of EB Sledge in training. At the very least i think we can expect to see him before the war, which would make sense because we'll see him after the war. I really would be fine with Gloucester being one episode while showing a bit of Australia and Pavuvu. I would really like to see them cut down Peleliu to two episodes and Okinawa into two. Okinawa is a battle that deserves to be covered extensively especially when the Okinawa episode (I assume) will also show Sledge after the war. That way it won't seem like Okinawa was rushed. Other than that from what I've seen and heard this series will be great and will do great justice to the men who fought in the Pacific.

I think they will shorten the Iwo Jima battle a bit since Basilone lost his life on the first day of the landing February 19, 1945. Hopefully, they will show the landing on Okinawa during that episode.

True and they may also show a little about Okinawa in April because the battle picked up for Sledge in May. I'm guessing they will do something like that, at least show the landing on Okinawa. That way it won't feel completely rushed.

I agree with wanting to see more of Okinawa and with Iwo not taking a full episode.

As the series focus is not the 5th Marines, the only reason we’ll even see Iwo at all is because we’ll be following John Basilone into combat again. As mentioned, it might be difficult to devote an entire episode to this as Basilone died just beyond Red Beach II. (Unless this episode also covers at length his return to the states, War Bond Tour, request to return to combat, etc…And even then…)

As mentioned in previous posts, Sledge spent more time on Okinawa than he did on Peleliu, so I’m not sure just one episode on this subject will suffice. The entire second half of With the Old Breed takes place on Okinawa, a populated Japanese prefecture and one of the largest and deadliest battles for US forces in the Pacific. (For the US, a bigger prize at a bigger price than Iwo, though a slightly less deadly engagement for the 1st Marine Division than Peleliu.) I’d like to see two episodes devoted to it if only because it’s never covered dramatically.
