I'm super confused as to what paying for increased defense actually does. I pumped Hill 712 full of defense spending and it didn't seem to affect the defense missions for it whatsoever.
Also, I am utterly at a loss as to the point of the beach landing entry method. All it seemed to do the couple of times I tried it was to get my entire squad wiped out, as one or two guys die automatically in the landing craft and the rest get wiped before you can even manage to push up the second tier of the hill.
