The DoD does plenty of things beyond putting boots on the ground. They’re the world’s largest employer. They have all the same boring problems that any employer has at gigantic scale.

Such things are already in use in Palestine, integrating it into the broader US military will take some work.

One main function is to enable sloppier targeting while easing the PTSD load on soldiers, i.e. allowing for more criminal and genocidal operations without immediate mutiny or desertions.

In a sense you can make the computer more convincing to the operator and have it tag more people as supposedly threatening, e.g. to up the amount of supposed threats in a gathering from one actually militant person to several based on aggregation of sentiment analysis, network analysis and so on.

You might understand that you're looking at a wedding, but the computer says several people there are 'red' because of social media posts, who they had lunch with a while ago and so on, raising the threshold for when so called collateral starts to hurt your operators badly enough to be a problem.

And then you have the dream of autonomous swarms of machines doing murder, which I'm sure the current US regime is salivating over and likely hope that these corporations will be able to help bring about eventually. Imagine going from a cop street murder that gets bad press and court proceedings and so on, to instead having to handle a set of Jira tickets due to a supposed bug.

why? it could help them asses threats, civilians / avoid collateral damage. Like any weapon or technology, it depends on its use. warfighter is the modern industry / academic term used for "soldier."

There is no "should" in war beyond winning.
