Interesting the NZ Army moving to mostly 7.62 rounds..
It's only one 7.62 weapon per squad... The whole SAM/SDM thing...
Americans and Brits have been doing it for ages... one member of the squad having greater standoff capability - just like one will have a SAW of some kind.
Good news though imo. long range engagements are typical of Afghanistan... although probably not so much for any of our "pacific insurgency" type conflicts...
