On friction, I found Boyd’s critique of Clausewitz already addressed by Olivia Garard @teaandtactics.bsky.social.

Boyd believed Clausewitz did not consider maximizing the enemy’s friction. Clausewitz minimized this because it was usually not possible. 2/

As Clausewitz says, in war it usually takes all our effort to achieve even mediocre results. We usually can’t spare any resources from our main effort, whether that is attacking the enemy or receiving theirs. This decisive point is what Clausewitz argues must be prioritized, not friction alone. 3/

This brings us nicely to the Schwerpunkt, or center of gravity. This is a term that gained popularity after Clausewitz used it but in a largely different sense, to mean the “main effort.” Clausewitz invoked the analogy to explain how the movement of one thing could cause the movement of others. 4/
