The gig isn't a year-round job, and it's not a paid position. The squad typically convenes for months-long training sessions before big events, like the Olympics.

There are stringent physical requirements for joining. The cheerleaders must be taller than 5'3, and have a round face, large eyes, and clear, high voices.

The squad members are all their late teens or early 20s. Former cheerleader Ri Sol-ju — Kim Jong-Un's now-wife — was 16 when she performed with in the group in 2005.

The prospective cheerleaders must also be able to pass a background check. Anyone with relatives who defected is automatically out of the running. The same goes for cheerleaders with family ties to Japan.

Many of the cheerleaders are recruited from Kim Il-sung University, while others have moved up the ranks through other performing groups.
North Korean defector and ex-cheerleader Han Seo-hee said she was first picked out to perform in an orchestra group at the age of eight. From there, she was ultimately recruited to join the cheerleading squad.

As a performer, Han received elite perks like bananas and cosmetics. She said, when it came to training in rehearsal halls, the coaches were nice, but "expected perfection."

The New York Times reported that the cheerleaders also view having the opportunity to travel as "a privilege" and a major draw.

At the Olympics, the group's performances function as blatant propaganda. South Korea has put forward smaller cheerleading exhibitions, but for North Korea, it's more about projecting strength than entertaining the crowd.

Like the other North Korean athletes, the cheerleaders are never left alone. They must travel with both a South Korean and a North Korean monitor, at all times, and have to use the bathroom in groups.

If any cheerleader gets out of line, they could be punished. In 2006, 21 cheerleaders were reportedly sent to a prison camp for discussing their trip to South Korea after they returned home.

And defection is a nearly impossible prospect for the cheerleaders. The 500-person North Korean delegation includes numerous minders and informants. Their job is to surveil the athletes and cheerleaders, and ensure no one runs off.

And, even if a cheerleader manages to get away, they'd potentially be condemning their family back home to imprisonment or death. North Korea's propensity for collective punishment is actually why Han ended up fleeing the country.

After her brother fled the country, Han and her parents knew that they might be targeted. They ultimately followed him into China in 2006.
