I WAS sitting in the living room of an HDB flat in total darkness, when men in black stormed in with guns blazing.
I couldn't make them out, or even tell how many there were, as rapid volleys thundered around me and several spent cartridges bounced off my hand. Live rounds.
My only protection was the bullet-proof vest I wore, and strict compliance with instructions: 'Please stay within your seat in the red box. Don't stand up. And no camera shots. The men are trained to fire at flashes.'
Seconds later, the firing stopped and all was silent again. Of the shootout, only the pungent smell of gunpowder remained.
The lights came on and the dozen of us in the red box were shown the cutout figures of the terrorists and civilians that had been placed side by side behind us.
All the shots had been to the cardboard terrorists' foreheads. Instant death - if those cutouts had been real people.
'They are trained to recognise the terrorist and go for the brain stem kill,' said an officer with the Special Operations Forces, who are the cream of the Commandos.
This was the same unit that stormed the hijacked Singapore Airlines Airbus SQ 117 in 1991, gunning down all four hijackers and rescuing all 123 hostages unharmed.
Recently, I visited the secret training ground of the SOF.
High fences surround this four-storey building tucked away in a corner of the home of the Commandos at Hendon Camp in Changi. Few people other than the SOF men have ever been inside what is called the Close Quarter Battle building, off limits even to most Commandos.
Built in 1991 and upgraded in 1999, its facilities point to the crisis scenarios they are trained for, and the skills they strive to perfect.
Every other day, they practise in the firing range in their 'main battle hall' to sharpen their shooting.
They also blow up replaceable doors on one side of the hall for demolition practice.
Above the hall is a mock-up of an A310 Airbus plane fitted out with plywood figures of passengers on foam seats, and along the corridor, two panels open up to reveal a mock-up lift.
A maze of rooms in the multi-purpose building can be configured for any crisis scene, even one as mundane as an HDB apartment, complete with sofa set and coffee table.
They weren't prepared to show them all to reporters.
Secrecy is the watchword.
Even from family members. Warrant Officer Chan, 48, a 20-year veteran with the SOF before he took on a different assignment last year, said: 'My family knew I was in the Commandos, but they didn't really know what I was doing. My wife was very supportive whenever I couldn't be home or had to go overseas.'
Like many in the SOF, he is a father. He has a 17-year-old daughter and a 14-year-old son.
They were always in his mind when he went on a mission.
'But my priority is the mission, other people's safety and my safety.'

Super shooter: Unlike a regular sniper, a Commando sniper is cross-trained in reconnaissance and learns more shooting techniques. He is also trained to survive longer in the field on his own, up to 14 days compared to three days for a regular sniper.
