"Homogenous" elements of the state militia type circa Civil War or the more recent Guard and Reserves which also mobilize as a unit (athough MOS requirements may mean reassignment) are the reason for saving "Pvt. Ryan" or giving some thought to not killing another family of sea-going Sullivans, or whatever. Come full circle on this one. Homogenous was the least offensive euphemistic adjective I could think of for everyone you knew in high school. The genius of the Draft Act of '68 was that it was administered relatively consistently and fairly as a lottery and gave everyone (however non-homogenized)a chance to do their duty. It goes without saying that the fleas come with the dog.
