I must say I am 'really' enjoying this game. Actually exceeded expectations on so many levels. (Once I can name my units and the villages get random names 'I will never ask for anything again'.)

I had a couple of decisive victories on regular then got clobbered on Veteran. I then tried a regular game with some house rules, I bought no cobras or armor, I added no units if I had less than 5000 Political points.
I managed a 54pt Victory with a 16 US casualty rate vs. 17 VC, 5 NVA. I was unable to visit 4 villages. Held my breath with every chopper sortie... Fun!
Thanks again!
