So, you wanna be a priest?

I also agree that the presence of a senior NCO w/i the US ranks will add an interesting angle (be it the company 1SG, or Battalion Sergeant Major type), although, typically, the 1SG did not deploy with line units into the field.
As for the NVA / VC, I think the game covers most of the important figures. A political officer would create some neat variations, but from what I've read, we generally disliked by the infantry types (the political officers would whip everyone into a frenzy, but conveniently avoid the firefights). As for the VC, the only thing that pops into mind would be a counter representing political / military cadre. These men were very important to the recruiting and training of VC units and frequently found themselves the targets of ambushes or 'snatch' missions by US units for intel purposes. Other than that, civilians in the villages always created problems, but I don't know if we want to venture there at this level of the game.
Any ideas?
