The AR market is not just entertainment, Microsoft has been failing to build a viable AR helmet for soldiers for years now, after the latest-and-greatest fight jets got them.
Professional use too - think of how much simpler and safer ‘realistic’ training could be for deep sea commercial divers or oil rig workers. Live schematic overlays for aircraft technicians at work/in training.
Those are a few of the applications where an absurdly high unit cost/license fee would be gladly swallowed instead by governments or business.
Like other have said, very likely cases for tank rounds instead of arty given they were ditched in Gaza - but without a clear shot of the reverse hard to tell exactly what kind, they are generic containers until labeled for their contents. US made and supplied:
