There is a huge difference between front line and support branches. From my 8 years of doing Ops in Iraq and afgan, i've never decompressed and haven't had any problems in not doing so.
I've been lucky and not seen the full horrors of this war; I live in relative comfort, eat reasonably well and maintain good contact with friends and family back home. I am not stressed at all, and apart from the normal minor gripes, am fairly content on Ops.
There are many procedures in place that already cover 'duty of care' and decompression for non front line isn't the way forward.
From the reports of what happens on decompression, I am fearing that I will need decompressing after decompression!!!!!
