First, I must say that I am offended by your ignorant-assed assumption in your statement. I enlisted in the USN, served proudly as a Navy Corpsman (2 tours in Vietnam) assigned to the USMC's 3rdMARDiv FMF
"Even though folks are quite happy to perform any required military duty, it doesn't mean they like it, or want more of it, or that they want to do additional service in a unit filled with draft evaders."
This bullshit statement probably applies to a lot of draft dodging pukes from the late sixties but I doubt very seriously if you'll be able to put this tag on those who served as enlistees versus those drafted.
FWIW, I would strongly urge you to watch your mouth when it comes to 'slamming' a Vietnam era Vet - knowingly or unknowingly!
May I recommend the works of Ernie Pyle for your review regarding the matter.
