I'm not sure if this has been asked before but it's my understanding that there are multiple branches within the security team. This gets a little confusing and I'm not sure what team 130666 is meant to be a part of. Or if the team names/positions used so far are correct.

The names I've seen used before are:

Security Team

Security Management Team (the training video 130666 watched used this phrase)

Special Unit (130666's suit is meant to be a feature of the special unit)

Hazard Response Team ( this one was used in the official gsgw welcome kit)

omfg I'm so sorry for missing this ask for so long... I was at the event blog and totally missed it orz

If you still need this info...

It is kinda confusing because not only is canon itself sort of confusing about this, but the two words used for 'security team' (보안팀, 경비팀) both get translated to 'security team'.

anyway...

according to official merch (the gsgw welcome kit), there's two teams related to security : 보안팀 and 경비팀. here's what they're translated to.

경비팀 : hazard response team

보안팀 : facility security team

we also know that J3 belongs to the former, since he is 경비반장.

However, according to ep 212, here's the teams for J3 and Park Minseong.

J3 : 보안관리 경비3팀

Park Minseong : 보안관리 특수관리팀

Notice the 보안 in both their teams..

Anyway, from this we can see that the larger department is named 보안관리, and J3 belongs to the 경비팀 (hazard response team) inside the 보안관리 department.

보안관리 is also the name used in the training video for 130666. So all it tells us is that he belongs to this larger department.

So what is 보안팀 (facility security team)?

Best I can guess is that '보안관리 특수관리팀', for whatever reason, gets shortened to '보안팀'. This would make both Park Minseong and 130666 'facility security team'.

I've also seen people posit that the larger department as a whole gets referred to as '보안팀', but this wouldn't account for the official merch.

Nothing that was pointed out in canon itself.

I have seen people talk about how 'Haje' means 'tomorrow' in traditional Korean.

There's also Jaekwan - the name of the Disaster Management Bureau (JaeNan KwanLi Guk 재난관리국) is often shortened by fans to JaeKwanGuk (재관국). It is often assumed by fans that RJK is meant to symbolize the Bureau itself for this reason, with some people going further and assuming that this is opposed to Choi who symbolizes individual agents.
