I tend to discount initial news reports as they can be confusing. What we know for sure is that a CH-53 went down in Western Iraq with 31 Marines killed. The cause of the crash is officially Unknown. No doubt more will be known as time goes on. This crash reminded me of the CH-46 that went down during the invasion that killed 4 US and 8 Royal Marines [weather related].
A Marine convoy was attacked near the Syrian border with 4 killed. The Army lost a soldier in an RPG attack.
