Military Embedded Systems has an interesting article about the 'kill web':
Transitioning from the kill chain to the kill web
The article grounds its discussion in digital co-operation between the various military domains (such as land, sea and air) but in reality there is only one domain that matters - space - and how satellites can weave a 'web' over territory on earth.
The web metaphor is particularly appropriate, not because of the web/internet connotation, but because of what a real spider's web actually does: pick up vibrations so the spider can rush to the source of the vibration to kill/eat whatever is causing it.
Once satellites can map territory with the equivalent of a web that picks up 'vibrations' it can inform a Palantir type targeting AI to launch killing 'assets' from way up in space.
There's actually not much need for conventional land, air and sea forces in the sense that killing assets can be largely unmanned and most likely deployed without involving any human oversight from Kansas or anywhere else.
Which is why all these projects to build new ships, aircraft and military vehicles already sound totally misguided and why the SpaceX IPO is likely to prove a wise investment.
Who cares if an Ajax fighting vehicle causes soldiers to vomit when the most likely occupants of such vehicles in 5 years time will be fighting robots who never throw up?
