Just curious, "what if"

[-Baz-]

Hi everyone, I am just curious as to what would happen if there was a major war (similar to that of WWII), how would the strategy of the Army change more specifically SF? I am sure overall, the Military would start drafting people...but would they shorten boot camp and training? just to get people in and out...would SF training also change? I'm just asking about opinions and so forth, anyone with experience maybe in Vietnam would have a better Idea since it was also a pretty major conflict. thanks.
