Braking down several key factors here it's fundermental we start with one the most imperative area's that will make these warriors superior.

 Training 

The partisipating US forces representing BFVietnam have undergone training pro-World War 2 and it is very likely they learnt a many few lessons from World War 2 and how the US force's training underwent was altered to combat a equally advanced foe at the times, this being the Russians.

The first US Marines that touched down on Asian land during Vietnam key mission was one of the two things, to train the South Vietnam to defeat the North Vietnemese and Viet Cong(Vietnam: Lost Films). This meaning that South V forces have undergone training from US Marines which have superior training to US Army units in combat and pro-amphibious combat.

The final and most fundermental edge here is the fact that the US bring MACV-SOG, the Studies and Observation group is an elite unit and part of the Special Activities Division and bring training that is tasked with secretive large scale-combat operations where their training was to be able to defeat many Vietcong foes.

Weapons are a important area here and will make a differnece but training is fundermental, and thus overall I have to give this to BFVietnam's forces, they bring the slightly more advanced technology with training that involved being able to combat a more advanced enemy at the time and training that learnt lessons from World War 2.
