From the Marine Corps Times:
Commands are advising personnel they are not authorized to wear so-called KIA bracelets, pictured at right, which have become a popular method for honoring friends and family members lost as a result of the wars in Afghanistan and Iraq. Regulations permit Marines in uniform to wear bracelets commemorating prisoners of war and military personnel missing in action, called POW/MIA bracelets, but KIA bracelets are not approved.
No explanation given…
