WASHINGTON (AP) — Relatives of several U.S. troops killed during a 2009 Afghanistan battle that led to a Medal of Honor question whether some Army officers got off too easy for mistakes that led to four American deaths.In interviews for CBS' "60 Minutes" on Sunday, the mother of a Marine and the wife of an Army sergeant killed in the September 2009 firefight in the Ganjgal Valley said reprimands given to two Army officers in an internal inquiry were not enough punishment. The inquiry concluded that the Army failed to provide adequate fire against Taliban forces that had U.S. units pinned down.President Barack Obama awarded former Marine Dakota Meyer the nation's top military honor last week for saving 36 lives with repeated charges into Taliban gunfire during the battle.
