| The 
				service member, who has not been identified, was the sixth 
				American to be killed in Afghanistan this year.
 The incident came two months after a member of a U.S. army 
				training unit was shot dead by an Afghan soldier in the southern 
				province of Uruzgan.
 
 "The sacrifice of our service member, who volunteered for a 
				mission to Afghanistan to protect his country, is a tragic loss 
				for all who knew and all who will now never know him," said Gen. 
				Scott Miller, who assumed command of NATO forces in Afghanistan 
				on Sunday.
 
 Insider attacks, often known as "green on blue" attacks in which 
				Afghan service members or attackers wearing Afghan uniforms fire 
				on U.S. or coalition troops, have been a regular feature of the 
				conflict in Afghanistan, although their frequency has diminished 
				in recent years.
 
 Coalition forces have also tightened security and added extra 
				force protection measures including special "Guardian Angel" 
				units to accompany training units.
 
 The Resolute Support statement said the wounded service member 
				was in a stable condition but gave no further details, saying 
				their name would be withheld until after next of kin were 
				notified.
