The best joint operation I ever did was Operation Joint Gaurdian. It was in Kosovo not in Iraq but it involved airborne troops from the US and Italy and then aviation units from the US, Germany, Switzerland, Austria, England, and Italy. After the Airborne troops dropped in we flew out and picked them up and inserted them into other locations. It was basically a big show of force to show the people there that we may be drawing down but if you start your shit up again we can be raining hell down on you again within 24 hours. It truely was a great operation and working with soldiers from other countries only made it better.
