Guerrilla irregulars
The Viet Cong represent the irregular, guerrilla edge of the communist war effort. Where the NVA fields disciplined regulars, the VC rely on ambush, traps and intimate knowledge of the terrain.
Status
The developers have been clear about their design focus: rather than leaning into traps and classic guerrilla warfare, the game centres on the conventional military conflict between the US and the NVA. The VC sit in the background of that framing as the irregular side of North Vietnam's effort.
What to expect
Expect the VC to inform the faction's flavour and future content rather than headline the launch experience. Their identity — local knowledge, concealment, irregular tactics — already shapes how the NVA side plays.
