Like the 6 RCTs and change worth of mobile forces we see going after wolf supply lines to cut off their ability to sustain the assaults on redoubts. And the redoubts did work against the Falcons. Geneva bogged down multiple galaxies of troops. Normandy as well. Falcons resorted to orbital bombardment against geneva. Which means the idea worked. Normandy only fell because of “muh Scotland”
We can’t really evaluate how the redoubts worked against the wolves without stepping out of universe because the wolves were just slaughtering whatever they faced regardless of numbers, established logic in universe, and established logic in the novel itself. Nothing about the wolf story in HotW can be taken at face value in universe.
I’d rather stay on topic than rehash this here.
There are a LOT of improbabilities that go on in the BTU, not just with the Wolves. In TWOR it's an accepted position that a defensive position staffed by peer-level forces will take three times the relative firepower/manpower to take. That is, Three attackers (or equivalent) for every defender.
Defense is stronger, but offense usually settles decisions. (See: Blitzkrieg tactics in 1940), usually by cutting off the defenders from relief and isolating them.
which takes a larger force. One for one and you get a stalemate at best.
Yet WoB had peer equivalency with some superiority in tech, brian fortresses, an established defense plan with extensive backups and fortifications, and used more resources...and still lost when Devlin Stone and Operation SCOUR came knocking their doors in, using smaller forces that previously hadn't cooperated, much less worked extensively together.
Fortresses ARE broken-by plot, or by isolation and reduction, assuming competent people on both sides, with committed subordinates and adequate supplies and support, forts work as 'fire magnets' that have to be isolated out and reduced-which is the point of fortress doctrine in the first place-to tie down an attacker reducing the defensive works until reinforcement or relief can arrive to lift the seige.
your examples show fortress doctrine working correctly in some cases, and mismanaged grossly in others.
That said, going back to the original question, RAF Redoubts would be heavily dependent on a number of combinations, including bunker networks, trench lines, artillery positions, and obstacles to include minefields or equivalent. Point being you're not gonna have a short list, since to be of any use, you need pretty much something from everything, including mobile forces that can be deployed out to harass an investing attacker or spot for artillery and mortars.
that is, if you want it to work on more than the reputation of Devlin Stone (Or insert your favorite legendary leader here).
and I'll point out again; Stone used the same strategy The Master used, and that Amaris used before him-only with fewer resources. This doesnt' mean all of his subordinate commanders were incompetent or bad at the job, just that the whole thing hinged on a might-be instead of on certainties. Portions of the plan were executed well, but the entire plan was executed poorly because the entire plan was planned poorly in the prep phase.
