I really enjoyed the movie, especially for its sound teams ability to capture all the grotesque realities. I also second Rod on his observations, however I do believe they wore protecs and just RRV racks with their assault packs on the mission. Even the ranger batt CSAR team was photographed only wearing boonies as headgear and were later reprimanded by higher for not wearing body armor, even though they were out of water, in 100+ degree weather in the most severe terrain imaginable.
