NATO?
What does all of this mean for NATO? It might lead to a situation in which more countries adopt the round, but likely only after some bickering. It’s happened before: when most countries in the alliance developed around a .303 British cartridge, the US, on our own, decided that, no, the .308 was going in our M14. This lead, eventually, other countries to follow along, at just about the time we ditched the .308 for 5.56mm. Arms standardization in NATO has always been tricky, and it looks like we’re going to enter in a new phase of figuring out tough logistics.
