Will the army buy this system?
Unlikely in the short term, this tec is good but overwhelming.
It really a problem with many of the digital equipment right now that it gives so much info for the operator that in the absence of AI it takes way to much time to prosses them , it basically creating a bottleneck in decision making , since there too much data to analyze.
And it required a complete overhaul of that data infrastructure.
One of those digital platoon will have about , 30 guys running around ,each with more data then you had before(heart beat sensor , location data, audio feed, text chat , and a possible video feed ) plus about 4 drones. That more then 10X data been gathered and transmitted ,also this data need to be communicated and processed , but you don't have 10X man , and not 10X radio equipment.
And you also can't have local hubs like in the civilian world , you can't have 1 mortar shell take out the entire platoon internet.
You just don't have the ability to oversee everything , even down to the squad level it bit too much ,a fireteam leader need to manage a drone , a 4 man voice channel in fireteam , a channel with the squad leader and maybe the platoon, that is on top of the normal duties of the fireteam leader. As anyone who had to be in a voice call with 4 man yelling at each other , that in it self is quite a challenge.
Just imagine how chaotic your average CS 5 man lobby is , and go from there.
All of these can be solved with training and AI assistance , but these are solutions that will need a mid to long term to implement, so untill then technology will cause more trouble then it's worth.
