Future therapy/treatment for veterans of near future/ further future mass casualty conflicts
The setting I am working on is near future in a sense and involves veterans dealing with the aftereffects and trauma of war. However, in this setting war is extremely deadly even if not always fatal. More so than our current battlefields. For example, the use of loitering munitions is so prevalent that most infantry units operate from armored APCs with heavy active protection systems and dismount only if the situation calls for it. There is some light shielding so tanks, APCs etc. can take a few hits. Short of nuclear weapons (non-factor in the setting), the soldiers from all sides practically threw everything at each other over a protracted conflict that spanned years. Death is either very fast and unexpected via the use of PGMs or large explosives/artillery. Or slow and painful i.e., when armor piercing shots damage vehicles and maim the crew but don't outright kill them immediately because of shielding.
The result of this is that there are a lot of injured and physically disabled veterans. 347
By the end of the war, which ended in a stalemate with all sides hanging on by a thread, the majority of active-duty soldiers are heavily injured and or have major war related trauma. While not a majority, a decent percentage of each countries' population was recruited or conscripted during the war. The casualties were horrific regardless. Essentially to the point that the militaries of countries have to wipe away the majority of their armed forces and recruit or conscript from scratch due to the prevalence of severely injured soldiers (think <PERSON> levels of bad, but instead of the old and extremely young its mainly the heavily injured.).
With all these returning veterans coming back home there is obviously a major reintegration problem. Especially with how violent the war was. One of the issues is that the fighting didn't really affect civilian areas. Civilians no doubt had their own stressors and issues, but the fighting largely took place off planet. As a result, civilians including the academic/medical community back home have a different and less popular view of the war and the soldiers (think Vietnam).
Given the extra level of violence one could expect from close to far future conflicts between peer forces what would therapy/treatment look like on a systemic level. With the sudden influx of mass casualties returning from an entirely different planet at the end of the war, what medical and psychological advancements could one expect to be used to treat such a large group of returning veterans.
Edit: Focused question based on feedback to focus on future treatments instead of "upper limit" on treatments. 454
