SB Vietnam vs Tour of Duty

[WargameGeneral]

Hey guys,

I would like to get into Squad Battles; the Vietnam-related titles have caught my attention...

Apart from different scenarios and the campaign feature, what are the major differences between "Vietnam" and "Tour of Duty"?

I read in a blog post (can't find the link at the moment) that "Falklands" uses the same weapon simulation model that is used in "Tour of Duty". So are there any mechanical differences between those titles regarding the mathematical simulation of damage, weapons, probabilities etc.?

Are the scenarios more interesting in one particular title?

With which title would you start?

Thanks for your feedback...
