18 people signed up for this challenge. Are they crazy or just a bunch of sadomasochists? You decide.

Got pain no gain? Imagine undergoing 24 hours of physical and mental tests, passing, and yet not getting selected.

8 may not always be a lucky number. Unless you enjoy these 8 levels of pain...

They are in intense physical pain and under extreme mental pressure. Yet they're expected to be disciplined and responsive.

None of these guys have done it before, nor the one female among them…

If you’re going to be running among the dead, you might wanna do it a little faster…

There are no dead men walking, only 18 people running through treacherous terrain.

Challengers get started on the endurance circuit carrying a 18kg backpack.

Who's the first man out? ...Or is it a woman? We get the first sign that this test is going to be trouble for some.

It seems these hoses are proving to be a hell lot of trouble for some.

We've barely started, yet the tally on the board is piling up as another one calls it quits.

Anything a man can do, a woman can do better. One woman proves it right here...

Apparently it's not a man's game. The girl's made it through, but why are some guys still not getting it?

6 out of 18 fail, proving it's more than just raw brawn that works. Could this be the end for some so early in the game?

How would you like your beef curry? Mushy and squeezed from a packet? After two gruelling tasks, that's all they get for lunch.

It's not over till the DART Commander says so. That's good news for the six candidates who dropped out after Test 2.

The candidates are looking forward to a cool dip in the pool, but for some it could be a daunting 250 metres to get through to the next test.

A wet end. Things don't end well, as the DART selection process records its first official elimination.

Things are heating up, as this year's DART selection test drags on into its 7th hour - and under the hot afternoon sun!

Meet "Big John". He's a solid 90 kilos, and he's about to get you all hot under the collar.

If you're not already half dead from 7 straight hours of physical exertion, trying to complete the tasks in this test may finish you off.

Getting all hot and steamy in the sauna may not necessarily be on the top of everyone's list of places to be stuck in.

Everyone has a go at 'Big John' - you have to get past the big guy if you want to get to the good stuff!

Two more candidates drop out midway through Test 4, and they haven't even tried the sauna yet!

5 drop out. They're down to 12 men, as evening hits day one of the 24-hour DART selection test.

Find out what's most important to make it to DART team, as DART commanders call a timeout to take a dinner break.

It's back to the cemetery for Test 5 for the remaining 12 candidates in the DART selection process.

Find out which candidate appreciates the sacrifice needed to reach the final objective.

Night at the cemetery. As darkness falls, real fear sets in...

More often than not, rescue teams encounter the dead rather than the living, hence the start point of their journey is of utmost importance.

DART commanders throw down the gauntlet as the night wears on and fatigue and exhaustion is visible among the remaining candidates.

The candidates are issued an ultimatum - complete one lap in one hour, or else...

DART commanders reinforce a sense of urgency, as the hours take their toll on the candidates.

The candidates are pushed to the limit physically, but their mental resilience is sorely tested as they are goaded with images of comfort and home.

The candidates' reasons for wanting to be on the DART team varied, as DART commanders tried to break their resolve.

The candidates have busted the 4-hour deadline by a good 2 hours, and still one lap shy of the 21km required to complete the Test. But after 6 straight hours of walking - and the weakest links eliminated - DART commanders decide to call it a night.

A hammer, a chisel and a torchlight. Simple everyday tools, but they will save a life when you're up against a wall.

After two tests involving team work, the remaining 8 candidates are now on their own to be tested on their solo survival skills.

One by one, brick by brick... the candidates chisel away at the wall till they can fit through it.

It's almost 4am in the morning. After almost 18 hours and 6 tests, the DART candidates are expected to be alert to emergency sirens and to react accordingly. Will the 8 make it succesfully to the emergency evacuation?

Should I carry on or not? It's all in the mind as the remaining candidates start feeling the mental drain.

A whistle signals the end of the Solo Test. Did all 8 manage to breech the wall? At this stage of the challenge, these guys have to be in it to win it.

It's been 12 hours since the candidates started this challenge. Welcome to day two of the DART selection process. Will they get enough rope to see it through to the last test?

This test is not for you if you're fainthearted and afraid of heights. The eight remaining candidates harness up and get ready for the scale and rappel height confidence test, a skill most essential in suicide rescue missions.

DART Commander Alvin Tan feels that none of the candidates are prepared for the test. What made him draw that conclusion?

Who aces the test, and who flubs it? Find out...

Need an adrenaline rush? Then go no further than this test. It's guaranteed to make your pulse race.

The remaining eight candidates breeze through the Height Confidence test, but they're in for a surprise when DART Commander Alvin Tan demands a re-test.

It's back to the BA Maze for 5 of the 8 candidates, as DART Commander Alvin Tan demands a re-test at the endurance circuit.

It's take two for those who failed the time limit for the BA test first time around. Will it be second time lucky for these five guys?

Said made record time on his re-test for the BA Maze, so how will Razif and Nazmin do?

Is the end almost in sight for our 8 candidates? Are they all clear to proceed to the last and final test in the challenge?

After more than 24 hours, 7 physically and mentally demanding tests and one re-test, 8 candidates remain to take on the final challenge.

Fazly and Kelvin are the guinea pigs, as the first team of two attempt the Tunnel Simulator.

Nazmin and Shahafashah are next to enter the tunnel, as DART Commander Col Alvin Tan gives his assessment of the candidates.

DART Instructor Capt Jason Chua reminds all that this is only the beginning for any successful candidate, as Zulhaidi and Said take their turn in the Tunnel Simulator.

Gani and Razif take up the tail of the Tunnel challenge. So, do these guys have what it takes to be a DART specialist?

It's finally over for the 8 remaining candidates as they hit the finish line with the completion of the 8th and final test of the DART selection process.

Who made it and who didn't? Was all that hard work for nothing? DART Commander Col Alvin Tan gives the debrief, as he stresses the important characteristics that will determine which of these guys will make the DART team and become DART specialists.

Some of the candidates give their take on going through the 24-hour DART selection test, and offer some advise for future candidates on how to train for it.
