A Minnesota soldier is among those killed in the shooting rampage at Fort Hood. Kham Xiong, of St. Paul, died in the attack.
Meanwhile, Army Chief of Staff George Casey has asked army leaders across the country to review force protection measures.
Casey described the shooting as a ``kick in the gut'' for not just fort hood but for the entire army. Authorities believe Nidal Malik Hasan, an army psychiatrist, killed 13 people and wounded dozens others.
