5 RAR have lost 2 in a month. I remember my 1st ex in Darwin (8/12 Mdm Regt) they sent JNCO's out within 3 days of marching in, many from "down south" for a team building exercise.
A dozen or so went down with heat by teatime.
The post-ex debrief was everyone who went down with heat had to explain why they did. Worst case of bastardisation I ever saw and down right lack of common sense. Many were not acclimatised and had spent the summer on leave.
More recently an OC of 8/9 allegedly refused ambulances being called for diggers going down with heat at Canungra.
CFA's are not Paramedics....
