You would make a fine and honorable member of the U.S. Armed Forces, Central_Floridian.
The honorable conduct you advocate is not "political correctness". It is conduct mandated by the U.S. Department of Defense as outlined in Department of Defense Directive 2310.1: DoD Program for Enemy Prisoners of War (EPOW) and Other Detainees.
The willful execution of captured Enemy Prisoners of War that some on this thread advocate is a direct violation of the law of armed conflict and of U.S. Defense Department Directives. In the Waffen SS and in al Qaeda, such conduct may have made you a more studly soldier. In the U.S. Marine Corps, such conduct simply makes you a crimminal under the Uniform Code of Military Justice.
As noted by Marine Corps Reference Publication 4-11.8B: War Crimes Investigation, Chapter III, the willful killing of an EPW can be punished under UCMJ Article 92 (Failure to obey order or regulation), Article 134, (General article), Article 93 (Cruelty and maltreatment) and Article 118 (Murder).
If all Iraqi soldiers subscribed to the Waffen SS wannabe mentality that some on this thread portray as "non-Politically Correct" warfare, Pfc. Lynch and seven other American ex-POW's would now be dead with bullet holes in the back of their skulls.
