Abolish Tri-Service
I'll take the bait.
Abolish tri-service. There you go, there's the simple answer.
Australia could do no better than modelling its defence force on the US Marine Corps where every member of the defence force is a soldier first, where each is committed to a common uniform, language and capability, rather than what we have now, namely; each arm speaking a separate language and not being able to integrate when the sh1t really hits the fan.
Get rid of this archaic tri service set up which wastes so much infrastructure.
Top heavy bureaucracy is great when you go in a straight line, but the moment you need to maneouvre quickly it topples.
