The way things go there would be almost no people in the field, just drones of all kinds and occasional stormtrooper teams in extremely expensive stealth cloaks. Basically no human would be able to exist in the environment with several thousand drones per kilometer. And I don’t think much of these drones are going to be repaired , more like smartphones - nobody repairs them.

By the way, extremely important part, becoming even bigger and more important - the massive scale battlefield data intelligence gathering, including from all those drones, processing and targeting is done in Ukraine by Palantir in major part by their people deployed there. There is no real right-to-repair or ability to repair in the field when it comes to such software (or to communication networks like Starlink). With that background it is really small peanuts, which will take all the attention away from important things, whether soldiers can replace on their own an RFID-ed DRM-ed valve in the howitzer blowback hydraulics.
