The same way everyone else does it. With as much support as they can get.Tell us how you diggers in your Royal Australian Regiment do it.And let's be honest here. Most people beating people over the head with combat experience have had a billion dollar military supporting them.

For example I asked a special forces guy how you clear a house on your own Because I was basically doing that responding to break ins.
He laughed and said you don't do it on your own.
