"Efficiency vs. Effectiveness" is usually a false argument - it tends to emphasize local short term tactical effectiveness over broader or longer term effectiveness, which does not always equal the achievement of desired operational objectives or strategic outcomes. The reason you strive for efficiency is not for efficiency's sake, but rather to remain more effective in the broader scope of your operations, across the entire theater. The "take the bridge" analogy won't work for these kinds of operations, because there aren't 10 brigade commanders - you're probably talking about the ASBC equivalent or two or three max, all sharing the same sustainment brigade. We won't have the mass to make up for our mistakes if we don't synchronize, and gaps in defense, EW support, ISR, etc are created inadvertently by package commanders operating off of partial pictures of the larger operational situation. When you have lots of reserves and slack in your logistics, you can afford to be less efficient, but in the kinds of "operations at distance" ASBC is contemplating, you're only a couple assets deep in several critical mission areas, and some bad calls mean that airplanes start dropping out of the sky due to fuel exhaustion or botched air defense lanes. So yes, the supported/supporting relationship thing is going to be very difficult, and may have to shift dynamically between different commanders dependent on the situation - when you're using the same asset for multiple roles (i.e. CRUDES for IAMD, surface warfare, ASW, and TLAM offensive interdiction), it's going to be tough to determine which assets should play which roles even within the a single functional component (JFMCC in this case). You can't decentralized the JFC authority to apportion and reapportion rapidly, and in some special cases, you may need centralized C2 to get the kinds of permissions you need from above the JFC level. Again, it helps to have one C2 point of entry for those - especially when you need to coordinate the timing of enabling effects (space and cyber) with national assets that not even the JFC owns.
