The Afghan point stands, though it's a common misconception that the North Vietnamese were very poorly armed. The Viet Cong were an insurgency group, but North Vietnam had a traditional army which was relatively well equipped for the era. Including rocket artillery (BM-21), supersonic jet fighters (Mig-21s), surface to air missiles (SA-2), and main battle tanks (Type 59, among others). I definitely wouldn't put their weaponry in the same category as "pea shooters"
