If you read the thread and his later comment, he is talking about army aviation, artillery etc for BAI and CAS, not strike etc.
In my view, a new combined arms drone/electronic warfare military branch is going to eat US Army aviation, artillery, air defense & military intelligence branches with a few unit names to mark their passing like horse cavalry.
Storm Shadow and the l8ke are good but expensive, smart stealthy platforms with cheap bombs and their own deployable swarms will remain cheaper per target and overall.
