The Special Forces have been labeled as the major cause of civilian deaths in Afghanistan, and this should be no surprise to anyone who understands the topic.
The SF selection process, warrior machismo ethos and now the Ranger bleed-over since the groups' cross-fertilization all conspire to create tabbed-up warrior critters psyched up to kill people, some of whom will be civilians.
The art of discernment is not a Ranger strength. No one should be surprised by this outcome, especially as the entire Phony War on Terror (PWOT ©) is an exercise at cross-purposes to itself.
I remember the days of a much different Special Forces and mourn its passing.
The old rule of thumb was that Rangers would work 15 kliks to the enemy's front lines, and SF would operate in and occupy terrain as far as 450 kliks to the front of FLOT. This concept has obviously been overcome by events since the U.S. military is no longer capable of fighting actual military scenarios.
I continue to emphasize, Rangers ≠ SF and SF ≠ Rangers. When the lines blurred regarding assigned missions, unit focus suffered. SF was always a combat multiplier and Rangers were direct action assault troops, sort of like Marines once they moved inland from the beach head.
