Apparently, the designers felt that to convey the 'Vietnam' experience, they need to throw troops out from nowhere. Give me a break. I can accept a troop or two sneaking around me and such, but troopers literally appearing out of nowhere is ridiculous. The sound becomes irritating as half the time it is useless to pinpoint where fire is coming from, and the other half it is playing some music so bad that I'm sure Vietnamese radio would find offensive. Beratement besides, there is actually 1 or 2 points with the game that are good.
Damage is taken realistically.
Your Super Sgt. can only take 5 shots at the very most before dying and the weapons are fairly accurately represented. Being able to use special commands for troops you run into is also a good feature. If only Nam had gone MIA, and presumed dead.
