May I ask, why you think it is indeed an official ASCC/NATO name? By my understanding this site is more a fan site especially when you look at the other data ... at least NOTHING (that I am aware of) hints towards NATO or an official NATO-related organisation.

It's not what I think, it is what is being stated by people who know it, who have confirmed the name after this particular information was conveyed to us in the last week or two.
Essentially, people who work in the business (active US military, or in US MIC, or others in the DoD/intelligence space) have confirmed it.
As if just anyone could have a DNS in the .MIL domain. .MIL is reserved for US DoD.
That is a US Army website.
It looks like a database used for wargaming. So it might not be 100% accurate.
It is accurate, just accept it.
The document itself is irrelevant, rather it just happens to finally released the name which has been in use for years, and multiple people with knowledge about it have confirmed it is the name, but they haven't been able to confirm it unless it was out in the public first.
