But if it's anything like the real IoT.
It is not. It is just called IoT to get some funding.
The whole idea is to have highly dynamic network of devices. Imagine you have absolute nightmare of a battlefield with tanks, ships, planes, drones, etc. And all this was pulled in the last moment, because there is some military operation going on and there is no time to plan. It would be (and is) a total communication nightmare if all of those units were to use plain old analog radios for communications.
A better system will use universal ad-hoc network, so that commanders could for example, get a real time video stream from a plane or a drone, at the same time have exact information on remaining ammo and location of all units.
The next step is to give all this information to AI and let AI do routine work, offloading people who actually understand military strategy and tactics. And may be over time AI on the command post can give direct commands to AI on all those units in the field.
There is a lot of really cool stuff can be done once you have real time access to the information.
