i played 6 or 7 more turns after i added 'ARVN Infantry'. i used the civ3 'Infantry' graphics. i simply copied it and renamed it 'ARVN Infantry' and, of course, changed the .ini
i also gave Vietcong the 'Invisible' flag and the NLF Inf. the 'Stealth' flag. I gave Green Beret Stealth & Detect Invisible and +1 HP.
i put the 'Land Mine' in as well. i gave it the unit creator's suggested stats...it's on a previous post in this thread. can't remember exactly

but it worked pretty good. the green beret 'saw' it and the others didin't. one land mine killed a Marine

. not sure if we should let the AI build them. really, it would be
whether the AI would build them and
then transport/airdrop them b/c they're immobile. maybe give Vietcong a flag to transport it? i dunno. but i think we can use them. btw, i saw a mech/tank unit at cdg that has that front-end thingie.
some playtesting...
hueys can transport 6 foot units and they have more than 1 mvmt pt. is this right?
i attacked the Pathet Lao and lost w/ a Green Beret vs a PL guerilla

though, i knocked them out w/ a few Marines and a Mortar, of which i added to the US. they're not available to the US in the .biq. i had to change it. they should definitely have Mortar.
N Vietnam launched a few Bombers over Dong Ha (northern-most s vietnamese city)
Thailand declared war on Cambodia and Cambodia attacked on the next turn. well, this forced the US into declaring war against Cambodia b/c of the 'Locked Alliance' w/ Thailand.
maybe we should allign cambodia and laos w/ Thailand, US and s vietnam. i know it's not entirely accurate. but we would want to prevent all of that alligned/unalligned entanglement stuff.
