It's a long video but he gives away all the main points:

1. A KATUSA is not expected to do anything more than converse in English with American troops. If a guy from Texas shouts something, the KATUSA has to understand it right away. Ideally, the KATUSA can also speak English well enough that the Texan understands whatever he shouts back. nyuug meets this criterion.

2. See #1. The KATUSA is not expected to do anything more than converse in English. Pushups and all that are optional. The KATUSA doesn't have to sleep with his combat boots on like his American roommate. He can geek out and do whatever, because none of the Amerians expect him to do a goddamn thing except speak English well in a jiffy.

3. Korean nationals fight like mad dogs to become KATUSA because the lifestyle is so chill even by US Army standards, let alone Korean army standards. These bastards can eat beef and mashed potatoes and drink coca cola just like everyone else in the US Army. No kimchi and rice. No smelly 50 year-old helmets and pleather boots. The facilities are even heated in the winter, and you get a mattress to sleep on. Everything a Korean conscript dreams of.

4. None of these Korean nationals can make the cut because they can't speak English for shit, only read and write. No one can understand them. Almost every Korean national who makes the cut lived abroad and spoke English in another country.

5. Every Korean woman heard every Korean high school boy say "I need to study my ass off to become a KATUSA," but they've never met a real KATUSA. So when they meet an actual IRL KATUSA, they're meeting the man every other Korean man was trying to become when he was 18.

Earlier in the video he says he would always wear his KATUSA uniform when he went out on Friday nights.
