Since that time, the defence force has been involved in many armed conflicts and peace keeping missions around the world — but with varying degrees of public support.

The language used to talk about mental ill-health can play a key role in reducing or enforcing stigma. And it's constantly evolving. But what terms should be used and when? And by whom?
