There's a whole thread dedicated to it on the first page. https://forum.corvusbelli.com/index.php?threads/28288/
That was in context of anti-material, but i agree with keeping future discussion about normal engagement with that specop setup on the linked thread :)
If you are asking just how does one go about killing another guy with this weapon, it's currently believed to be 3 arm saves against the monofilm rule. So quite a lethal blade there.
I would expect any move to disentangle Mono from other Special Ammo would also make Mono function against Total Immune targets. http://infinitythewiki.com/en/Types_of_Special_Ammunition In either case, when the combined effects involve the same Attribute (ARM, for example), apply both in the same Roll. http://infinitythewiki.com/en/Monofilament_Special_Ammunition Roll After a successful attack using Monofilament Special Ammunition, the target must make an ARM Roll. http://infinitythewiki.com/en/Explosive_(EXP)_Special_Ammunition Roll After a successful attack using Explosive Special Ammunition, the target must make three separate ARM Rolls.
Though what such a move'd do to K2 would be interesting. That said, I don't actually think it'll happen and it would be a bit sad to see the only unique thing about Yu Jing spec ops loadout go away. I write "unique" but, honestly, having only Cube spec ops and having a Cube option is unique in the wrong way...
Just because the JSA left their Cube option behind (since that’s what it’s left over from...) Who thought trying to have the same equipment list for all of the NA2 armies would work?
Yeah... JSA really should have Yu Jing list. There's some options in there that screams JSA more than Yu Jing.
