What if the deep battle doesn't matter?

The modern interpretation of manoeuvre theory for warfare holds the deep battle as a central avenue to success. Indeed, Western militaries have become so invested in this thinking that force designs and procurement prioritise capabilities for this over almost anything else. Yet, as Franz-Stefan Gady points out, what if our adversary is just not structured for the type of systems warfare that successful use of manoeuvre warfare necessitates? What if the deep battle doesn't matter, or – and this be heresy to many – centres of gravity just not relevant? Have we even thought about alternative approaches, let alone started educating the next generation of the profession of arms in them? A discussion that starts to turn our theory of battle upside down.
