Yes, I am aware of the fact that there are more than enought "überforts" made in sf_skywalk. And yes, I am aware that this is a rather common type of Überforting. But bear me for this one time please. As here is my first Überfort:
The main wall is made of two layers of 2x3 and one layer of 1x5 expect the sides, where it's one layer of 1x5. These are the only "weak-spots" of the fort.
The non-entry (B) bunker is built so, that the shooter must be kneeled to be able to aim thru the gap. The entry-side (A) bunker is built in a way, that allows the user to hide completely if needed. Both A and B and very hard to nade. Both have a FOV to about 1/3 of the enemy base. This provides a managable sector to guard for snipers: not too large and not too small.
The crawl is made so that players are NOT able to use the sprint-bug to quickly get through. Enemies heads are visible thru the roof and there is a shooting-gap on the side. All of the entrance is built so, that it is impossible to kill the player from enemy's side of the map when he has entered the crawl. However the crawl is easily defended from inside.
The ramps to the battlements are placed in a way, that allows them to be easily reached from spawn. You can sprint right up there in case of an emergency, if there is no time to get ammo.
