A well thought-out scenario. Do you think exposure to nitric acid could account to the unusual "orange" color of the corpses? Do you have any documentation that a military exercise was being conducted on the evening of Feb. 1 in the area of the Dyatlov party? In the vast expanse of Siberia, what are the chances that the Soviet military would be carrying out a major exercise in such proximity of the hikers? Wouldn't trees be damaged and tracks everywhere? Also, someone run over by a tracked vehicle would have crushed bones, heart, lungs, etc. This wasn't the case if the autopsies can be believed, which is questionable itself. So many pieces would have to fall in place: missile launches, bombs dropped, soldiers, tanks, etc. on the move that is seems highly improbable to me. But a fascinating idea and as always, who knows for sure?
