Yes. what he said. ^

Since I didn't see the reference in the change log and I saw all that armapirx listed above, I assumed the new change to 5.56 was a mistake.

da12thMonkey: Thanks for confirming that it indeed is a purposeful change.

Confirmed: The unit will rearm with 30Rnd_556x45_Stanag when rearming from a vehicle or ammocrate containing 30Rnd_556x45_Stanag.

However as armapirx states, the notifications are incorrect in the Inventory UI Dialog. Hovering over the items lists incorrect information.
