This very detailed (though speculative) analysis by Armchair Warlord agrees with yours.

How do you destroy an attack network?

Notice that I didn't say military unit. A military unit has assigned equipment, a defined area of operations, and clear lines of communication. Attack networks - generally but not always terroristic in nature - are far more amorphous, relying largely on a web of key people (leaders, technicians, financiers, "fixers," smugglers, system operators and expendable dupes) to create custom weaponry and deploy them in an asymmetric manner for maximum effects.

Here I am of course referring to the Ukrainian GUR's "Black Sea Attack Network," a NATO-advised effort to harass Russian Crimea and disrupt Russian control of the Black Sea, which has entirely replaced Ukraine's sunken or captured navy on the battlefield. This effort has several prongs: an aerial drone campaign, a sea drone campaign, a commando effort, and operations that could easily be categorized as pure terrorism such as the October 2022 VBIED [vehicle-borne improvised explosive device] attack on the Kerch Bridge. You will immediately notice that all of these lines of effort require very little in the way of infrastructure and logistics - you can build bombs and crude drones in a garage and guide them out of a living room.
