Has the military become too PC to fight the nation's wars?

Of course. One example could be late 18th century and Napoleonic warfare, especially during the US Civil War. Warfare was governed by a tradition of gentlemanly rules that hindered warfare. It was not polite (or in as we'd say today, not "PC") to shoot or target officers. It was not "PC" for officers to socialize with enlisted. Then you had people like Gen. Sherman who went the very un-"PC", total war route during his March to the Sea. It was effective but looked down upon at the time as being extreme. Those kinds of rules hurt our war-fighting ability. Those are just the examples that popped into my head but I'm sure there others.

SSG Carlos Madden - You mentioned "...socialize with enlisted.". Do you advocate that now? Before I go on a rant, what kind of socializing are you advocating?

Maj John Bell - I see your point, but I'm not "advocating" anything. I mean most and perhaps any enlisted/officer association would be frowned upon in earlier times. The Officer/Enlisted distinction was as much of a socio-economic class issue as it was about military order. The fact that you can grow up with nothing but become a successful officer illustrates we don't have that kind of strict class distinction any longer. I think if an officer from the 18th or early 19th cent saw the way our current officer and enlisted relationships are now they'd probably roll over in their graves.
