DV - Incorrect speculation again.
The 'core maritime role' has certainly not diminished, we are still an island surrounded by water who relies on the seas for our bulk trade.
Also I'm not aware of 'an overland Afghanistan type role' being pushed by anyone for MRA4 and I'm waiting to start the OCU (whenever that will be).
No one knows what the defence review will leave behind, especially you.
I would love to know where you get your information from..or are you just guessing to fill space?
