PS Project Omaha is a mod being developed for Post Scriptum that plans to 100% accurately recreate the Omaha landings.
These logs were used as Anti landing craft devices. With the ramp facing the beach they were meant to capsize any craft that rode up on them.
Just a suggestion, some of those log ramps were used to carry mines on top them. My best wishes to you and this mod.
