Unlikely to be functional lol, it was just put there to replace missing bushmaster that was taken for tests, doesnt mean it has belt system and belt there.
Nice!!! I wonder what effectiveness the ERA will have. It looks pretty thin so likely more for HEAT and will lack any kinetic effectiveness with the exception of smaller caliber rounds. Could even be applique/quick replace armor for extra protection against drones but it’s more likely ERA. It also is receiving next-generation composite armor so even if its just HEAT-based ERA, the actual armor will be more than enough.
