Besides, the infrastructure that once supported Betamax is long gone. 10mm Auto ammunition on the other hand still has existing infrastructure to support it, or infrastructure that could be easily converted to do so.

No one uses that stuff in combat though

I may be mistaken, but there's a notable lack of MP5s in HRT hands recently. They're using HK416s or other shorty M4s.

One was the lowered noise level of the MP5, even while unsuppressed, to reduce hearing damage and suppressor wear. Another was that friendly fire incidents with the MP5 were much less likely to be lethal since most kevlar is good enough to stop 9mm rounds, while you need a Level III or Level IV armour plate to stop 5.56mm NATO rounds (and that might not even stop AP versions). The need for AP fire was covered by one or a few members of a team carrying an M4. Yes, this article was written before the adoption of .300 BLK in M4 carbines for subsonic suppressed fire, but I'll get to that shortly.

"We use 9mm so we don't kill each other" is the dumbest possible reason to use a MP5. Stop shooting each other!
