I was a little disapointed in the last few episodes, would have liked to see the shock an awe factor after finding out they vaporized over 100,000 people in the 2 bombings with this secret weapon.
I also would have liked them to show the roles of the scout dogs on those islands, normal house pets before the war turned into hero's that saved countless marines, I think there were about 600 of them and a lot went back to their familys after the war.
