I looked for information on this a long time ago for Wargame: Red Dragon. However, it may take some time because it is sleeping ‘somewhere (literally)’ in my old HDD.
They will play similar roles in the game, but technically there are two lines: Hyundai Rotem’s KW1/2 (K806/808) and Doosan-Hanwha’s Tarantula-Black Fox-Tigon.
I think Tarantula should be given priority because it did not sleep in the prototype stage and was actually mass produced and operated by the Indonesian Army… or why not have both in this tree?

Black Fox also has pictures of this, but I’m not suggesting it because I’m not sure if this turret is a mockup or actually works.

I cross-checked it through two sources.
First, I found this name on Jajusibo, an Internet news outlet written by pro-North Korea journalist Han Ho-seok. After visiting the 조선인민군 무장장비관Korean People’s Army Arms and Equipment Museum in Pyongyang, he wrote five chronicle articles, and the name “자행화승총Jahaenghwasŭngchong 10형10hyŏng” was mentioned in three of them. #1 #2 #3 #4 #5
Of course, as you can easily see, his claims are full of nonsense regarding the performance of North Korean weapons or the capabilities of the North Korean military. However, there is no reason for him to make up the ‘names’ of the weapons that he ‘wrote down’ during his visit to Phyŏngyang.
Second, I found this name on an article by Pastor Choi Jae-young that appeared in Minjog21, a pro-North Korea magazine. Like Han Ho-seok, he also visited the Korean People’s Army Arms and Equipment Museum in Pyongyang. He wrote “자행화승포Jahaenghwasŭngpho 10형10hyŏng”, a slightly different name than what Han used. It looks Choi confused the name with “고사포Kosapho (Anti Aircraft Gun)”.

Based on the two articles above, my conclusion is that “Pŏngae” is assumed to be the name of the missile, not the name of the entire system with vehicle. (Just like we don’t call North Korean ATGM-equipped vehicles “Pulsae”.)
In game, modifications like this are not unprecedented. The 2S6 gains radar and optics as well as missiles with the 2S6M1 upgrade.
