Headscratchers / Battlefield 4

• The Chinese have no business invading Singapore, Thailand, North Korea and (implied) other Asian countries. The PLA in real life practise a non-aggression policy (you don't offend me, I won't offend you), and this is a civil war (it's rare for a civil war to involve foreign nations, what more getting invaded). It's speculated by some fans that Chang's faction is helping establishing the Pan-Asian Coalition, but whether it's true remains to be seen.
  • Maps in the Final Stand DLC seems to indicate that this is the case, as several maps feature prototype PAC tech. Their presence in North Korea makes some sense as it could be seen as a response to a US invasion of the region with the PLA coming to aid the North Korean forces (which is what happened in the Korean War). Also, considering that Chinese forces in the game are also fighting Russian forces (who the campaign outright states would be loyal to the Chinese admiral), it's possible that Jin Jie and Admiral Chang each control their own faction of the PLA, with the latter being considerably more aggressive and prone to invading other Asian nations.
  • Not even the Singapore Armed Forces appear in their home level. The SAR 21 and Ultimax are there, might as well show them defending their homeland.

• Why do the Russians/Chinese have a gunship deployable as commanders? If I'm correct, it's the AC-130, why are they even using the AC-130? Wouldn't they be using something else entirely?
