How the Bali bombers will die 

They will be marched at night into the Indonesian forest, with reflective tape on their chests marking the position of their hearts.
  
Waiting for the three Bali bombers will be a team of executioners, armed with high-powered rifles.
  
At that moment, the bombers' choices will be few.
  
They will be tied to posts and given the option of standing, sitting or kneeling to await the bullets that will end their lives.
  
They will be asked if they prefer a black hood or a blindfold.
  
Moments before the executioners open fire, the bombers will be allowed a final prayer or statement.

Their lawyers are expected to be present to hear any final words they might utter.
  
If the executioners - drawn from a crack squad of Indonesian police - fail to kill the bombers immediately, the overseeing commander has the option of delivering a coup de grace.
  
And there will end what began on October 12, 2002, when Mukhlas, his brother Amrozi and Imam Samudra carried out their plan to kill Western tourists with bombs at crowded Bali nightclubs.
  
It was an act that sent shockwaves around the world, and sparked an outpouring of grief and anger in Australia, home to 88 of the 202 people killed that night.
  
Indonesia concerned about reprisal attacks from militants who support the bombers, has thrown up a tight security net on Nusakambangan Island, off Central Java, amid intense speculation the bombers will go to their deaths just after midnight on Saturday.
  
The Indonesian government does not make public the exact timing of executions, but has said the bombers will die in "early November".
  
Officials are not releasing any new information but some details are known about how the bombers will live out their final hours in isolation cells at their high-security prison.
  
They will be asked if they have any final requests. Typically these might include a visit from a religious figure or teacher, special food, or phone calls to loved ones.
  
Samudra - the field commander for the 2002 attacks who once fought with the Mujahideen Islamic militant group in Afghanistan - said in a will released a year ago that he wanted his body to be wrapped in cheap white cloth.
  
He also said his family must not shed any tears when his body is returned to his village in Serang, West Java.
  
But just how to return the bombers' bodies to their families poses a security challenge for Indonesian authorities.
  
It has been suggested the bodies will be flown out by helicopter to their respective villages, in east and west Java, for the burial within the 24 hours stipulated by Islamic law.
  
An airlift would avoid the risk that a land convoy could be targeted by the bombers' supporters.
  
The bombers have warned that others will take revenge if their executions are carried out, and Indonesian authorities are not taking any chances.
 
Hundreds of security personnel have reportedly gathered on Nusakambangan Island, with heavily-armed police patrolling the roads.
 
Critical infrastructure in the district, Cilacap, is also under guard, including a power plant and fuel depot, in case of revenge attacks.
  
The preparations are justified given the unrest that surrounded the executions of two Nigerians in June for drug smuggling - two inmates that had none of the bombers' ability to enrage and inflame.
  
When the Nigerians were informed they were about to be executed, a riot involving dozens of death-row prisoners erupted in the jail.
  
The inmates torched several rooms in the prison compound, prompting authorities to reconsider the processes under which prisoners are notified of their imminent deaths.
  
Indonesia has executed six other death row prisoners so far this year, Human Rights Watch says.
  
Another 100 prisoners remain on death row, including three young Australian men convicted over their roles in the failed 2005 Bali Nine heroin smuggling ring.
  
For drug mule Scott Rush and Bali Nine ringleaders Andrew Chan and Myuran Sukumaran, the bombers' executions will bring into excruciating focus the fate that awaits them.
