The "Archangel" team had to establish contact with the Intel team in specific coordinates for updated info on the location of the hostile forces in the area of operations. This team was infiltrated in the area long enough to have earned the trust of the local population, so their information was critical to carry out the rescue mission undetected. The radio contact could only take place at specific times. Regarding the pilots, one of them was unconscious and his location unknown, while the other could communicate and walk. Radio contact with the pilot was also subject to certain times. Recreating as the best do As it could be expected, Murphy decided that communications were overrated and there was no way to contact ... pretty much anyone. In the preparation stage we calculated ranges of effective communication in all key points of the exercise, with various equipment and frequency ranges, but when the time came, everything fell apart, surely this rings a bell to some of you.
