i tried a few times sea fort before me and Taff went air assault, i went for the sea assault, those ladders was my biggest problem, i could climb 1 , then fall off at the top, not even moving forward,
the few times i did manage to climb to the top, only by standing on top of 1st ladder and hoping for the icon to show on next ladder, by the time you get off the top ladder and retrieve your gun the ai right in front of that ladder kills you , so basically from attacking from sea forget it , your never going to get in there, to make it worth attempting... i think the ladders are apart of the design but if something can be changed about them would really be a lot better than those ladders , and as Taff said something to hide behind even if its just on the wall each side where the entrance ladders are, would make it alot more worth attempting this feature
