SM, please read before you post. "if it wasn't the army, it would have been something else, such as lightning" or an arsonist or a kid with a box of matches.
"We have had a cycle of 6 years of heavy rain and humidity" don't forget high temperatures as well. With Abbott and the like minded, and their do nothing policy, please prepare for even more cataclysmic weather events as the planet warms.
You started this discussion with condemnation of The Greens. now it has been established that it was army boneheads (most of whom vote Liberal) that caused the fires, will you now condemn them. Why don't you say as well people living in timber houses in bushland deserve to have their homes destroyed by fire, silly people.
"The only ones preventing this safety barrier have been the greens." where is your evidence. "The blood is on their hands." The only ones at this stage with blood on their hands are Liberal voting army boneheads, in the future it may well be do nothing political fools like Abbott with blood on their hands.

Paul,

Did you ever study physics?
Live ammunition in the ground does not start fires, it may explode if there is a fire but until then it just lays there doing nothing.

With typical Green's exaggeration you blame Defence for all the fires although it is 77 kilometres from Marangaroo to Springwood,

Three homes were lost to the Marangaroo fire not
"..... and destroy a couple of hundred homes." as you rather exaggeratedly claim.

Your other wild claim, as you desperatedly clutch at straws: "Now it has come to light that its not The Greens who are responsible for the fires in the Blue Mountains but some Colonel Kink (sic) fool and his band of bods from the army."

The Army was responsible for one fire but not the others (Hunter Valley??) they had nowt to do with the stupid policy of most councils in making it extremely difficult for people to clear dangerous scrub and trees from their properties.

The 'Black Saturday' fires in Victoria amply demonstrated that Green's influence in society is an evil thing that has cost lives and the Greens have blood on their collective hands, no matter how much they attempt to weasel out of it

Paul here is the Rural Landholders Guide to Enviromental Laws in NSW, I'm not sure if it wins or looses you your argument, but it is relevant. Enjoy.

<Live ammunition in the ground does not start fires, it may explode if there is a fire but until then it just lays there doing nothing.>
Maybe not but it does prevent immediate fire fighting efforts. I get that the Army has to train in such conditions, as war isn't going to take a day off for heat and wind however if the ARMY had measures in place to stop any resulting fires to get out of control crisis would have been adverted. But maybe the Army are not allow firebreaks either.

Bec,

It was live firing that started the fire not un-exploded rounds or bombs.
I've persona;;y set the bush on fire at Holdsworthy range in NSW, firing .50 cal Browning machine guns using tracer ammunition but we always had a fire truck standing by; so no problem.

Bec is mise is quite right and highlights a truth that should not be ignored.
Fires in firing ranges are nearly always fought by the Army for obvious reasons.
No answers to fire in this event, it was one of a great many, look if you wish at the idiots of all ages who lite them.
But ignore the dry bush at your peril, we should question what if any impact climate change plays in the rising number of them.
Bush fire season has not yet started if we look at past years events and timing.

Bec,

Thanks for the link, its all about responsible and sustainable management of bushland, that is the philosophy of The Greens. There is nothing preventing a landowner clearing around their property as per the act. One of my sons lives in the bush, has legally cleared around the house and most of his land was cleared years ago. like so much of our native bush was cleared for farming with little regard for the environmental consequences, in today's more enlightened times we have better management practices.
Some however, for their own ignorant and/or selfish reasons would wind back to clock 100 years and call for open slather.

"I've (Is Mise) persona;;y set the bush on fire" Well what can I say. I see why you defend the army boneheads who are reasonable for so much destruction.
"it is 77 kilometres from Marangaroo to Springwood," Google Maps, is that an army thing?
"The Army was responsible for one fire but not the others (Hunter Valley??)" How lucky for those who's homes were destroyed by those others.
