Far less than they used to. Before the 90s it was a pretty high percentage but now not as many. I have 2 nephews that went from the core into the militaryWhat percentage of the aggy corp served in the military after graduating? Kudos to them. But, of all the ones that I have known, there hasn't been one that has gone off to serve (except for 2 WWII veterans that were an aggys. I also have known old Texas Exes that served during WWII and Vietnam.
But since then, no "younger guys" that graduated after 1980 that I know, from aggyland or the 40 acres served...
