I am not sure how much was planned, but on the topic of planning you should always have contingencies with built in preparation for many other contingencies it is a more effective way.
So as you fight for attempt A, you seed attempt B C D E etc...
And if action B is needed, it also prepares for effort C D E etc...
At any time when the program executes out with proper results, the prepared events can be used elsewhere or allowed to grow wild until needed later, but if more extreme methods are needed they are already prepared for, and any other needed action is always pre-cooked and ready in the program to be used if it is required for later.
I think that is a better logistical approach to situations.
It is alot like throwing the ammo ahead scene in this video (3:52). (although I don't believe in violence) you can see how even while on area R he was preparing for section S or T.

McCain even noticed that, or I think that was the reason for his comment of what he learned, indicated by the comment always clean your musket before going into battle. Also the guy trying to wipe out feeling at the beginning of that clip is the bad guy in that movie. Empathy is a good thing.)
Maybe its easier to explain it like this, say you are taking a town to set up a farp that's plan A, so you devote offensive resources to take town, and have the farp construction unit rolling behind it. Now if A is not taken quick, you have a different town nearby to set up Farp, call that plan B, but the reason you roll your fueling construction apparatus behind the offense is so that if A looks like it is being stalled, you can send it to B, And the road you pick is not the fastest to A, but one with access to A and B. Also you assign enough escort with farp constructions to take B, even though it might just roll into A if plan A works. But garrison would be needed to free up A offense anyway, so for either plan A or plan B, you have the same set up Offense force, and behind it some time scale a construction force with an escort.
Now if A and B both stall, you could have an issue, so you set up a farp in your own lines so you would not have a fuel problem, but no need to fuel it, instead have the fuel convoy run a bit behind the farp construction convoy so that it could go to behind line farp if plan C was the one that ended up, if A or B succeed it rolls on to the that Farp.
The total plan is a mix of many plans, no individual part must succeed, but if any do, the plan succeeds, then you add to that other units in other plans, and how they interconnect with different success or failure of subsets of their plans. Same thing with air cover, it could be allocated for A B C of one or many plans, depending on need, but set up is to have the flexibility in place for assigning it where needed.
If the C farp is not needed, you use it for some other purpose since whatever security is needed is already known and foundation is already in place.
Meanwhile you have a whole other set of layers used for reinforcement, forward projection, defense and whatever else is needed, the more layers and interconnectivity the better.
