Lost Artwork — American Soldier Of The Future

Apparently I just lost the files for this awhileback and all I have are the old images I posted to discords. I'll update this if I find more.

This was based on that old Soldier of the Future concept. I also spun up a bit of flavor text for it...
Summarized, apparently this was a 1960s alternate history. That is an M14A1, and the first large fight this equipment went into was an Indian Civil War. Because of widespread antiballistic missile systems, the only way to destroy the enemy with nuclear weapons were tactical and cruise missile systems.
PACT lands on the moon first and apparently even gets to MARS somehow. NATO stabilizes in the 1950s and begins trying to widen the gap again.
Apparently there is a Pacifica Commonwealth, which I can only assume is a third faction in the South Asian region for common protection, and it falls apart during the Indian Civil War.
