Okay, I was enraged at looking at today's news.
Apparently that 3SG who died in the Land Rover accident and the
PTE who died from smoke grenade fumes were the victims of gross
negligence.
The Land Rover driver had been unlicensed. That alone is a
massive breach of safety.
And six smoke grenades had been thrown in the same spot. From my
experience, just one or two grenades in the same spot can produce a
thick smokescreen, and besides, anything more than two is a breach
of TSR.
I swear, there is still not much of a safety culture in the
SAF. 
It begets more questions, like why did they use 6 smoke
grenades? Were they trying to get rid of old stock? Why were there
excess grenades.
I hope it dispels, once and for all, the notion that the
chap died because he was "soft" or "weak".
