Top End beach under mock attack by USA, Japanese, Australian troops

A deserted beach south-west of Darwin is under attack in an exercise involving United States Marines and Japanese and Australian soldiers.

Fog Bay, about 70 kilometres south-west of Darwin, is where the Talisman Sabre 2015 exercise is underway.

The exercise is described by the Australian Defence Force (ADF) as a "biennial combined Australian and United States training activity, designed to train our respective military forces in planning and conducting Combined Task Force operations to improve the combat readiness and interoperability between our respective forces".

interoperability - you keep using that word.
