Yeah one of the uses of a MRE is an IED. I used one in the past while in the Army....
to add further I think we should return the favor to the insurgeants and let them feel a few iED's at their back door..it may be sinking to there level but it has been said the best tactic is to fight fire with fire....But aside from all of that I give alot of credit to our boys over in Iraq on a daily basis they face a large number of threats and even go in harms way for civilians they have never met or know....Humanity what a wonderful condition.
