I don't have any books to recommend, let alone 'neutral' sources, but two research 'areas' may help: 1) The USMC reading list. If you want an English language view of the current state of 'thought' from the leaders of any near-future conflicts, this list is it. It goes from poolee to the top brass. Maybe look for the more top level books and read from there. Though the underlying mindset is important and is from the lower rank books. https://mca-marines.org/commandants-professional-reading-list/ https://mca-marines.org/commandants-professional-reading-lis... 2) The wikipedia articles on the Nagorno-Karabakh war of October 2020 and their linked pages. Obviously there aren't any books out on this war yet, as it was so recent. But the underlying mechanics of the war are likely to be the ones we're seeing in the near future as both sides were somewhat evenly matched and had access to modern weaponry. "The war was marked by the deployment of drones, sensors, long-range heavy artillery[99] and missile strikes, as well as by state propaganda and the use of official social media accounts in online information warfare.[100]" I'd maybe put out a google alert for books about this conflict when they come out. https://en.wikipedia.org/wiki/2020_Nagorno-Karabakh_conflict https://en.wikipedia.org/wiki/2020_Nagorno-Karabakh_conflict
