[JURIST] The US Army is investigating 18 reservists in Iraq and could file charges after the soldiers allegedly refused to complete a supply mission last week, claiming their safety was jeopardized by vehicles without armor or adequate repairs. Brig. Gen. James Chambers said the incident was isolated and was not affecting resupply efforts. The Army is considering whether the soldiers' actions could be a violation of the Uniform Code of Military Justice. The troops were supposed to help in a 150-mile convoy trip from Tallil Air Base to Taji, north of Baghdad. The troops were detained and then released following their refusal to participate in the mission, AP reported. USA Today has more.
