In every instance you cite, what we see is bravery or fanaticism, not backed with skill. Thus, the overwhelmingly lopsided casualties. Part of me thinks the Coalition troops quoted give some props to the Iraqis out of Western guilt or appreciation of the underdog. Sure, maybe if our troops didn't have body armor, air support, and the other superior technology, the Iraqis would give a better showing, but those Scots didn't have that and still wiped the floor with them.
If you read the new book, Machine Gun, it is a fascinating story of how labor short Americans had to find machines to compensate. US ingenuity is probably no substitute for good fighting skills, but integrated as a fighting skill is perfectly honorable. A good job well done, is what is needed, and not some waste of human AllaAkbar sewage.
Hand to hand skills are transferable in terms of philosophy to "higher" forms of killing.
