Pilots coming from a purely military background may have very little knowledge of their liability in such cases, if it exists at all. It's a very grey area from their point of view I'd guess. I parked my T-38 in a row of GA aircraft at RNO sometime in 1984 while on a Cross Country because that's where the FBO told me to park, and in the military you park where you're told to park. When the time came to leave, I was VERY aware that my exhausts were pointed directly to the line of Cherokees and Cessna's behind me. I asked to be towed out before starting, pointing out the fiberglass bits of the planes behind me to the line guys. They told me they had insurance and it would be fine. Being military, we complied with the local authorities, started up and taxied out as gently as we could and departed.
Totally sucks that you took the brunt of this situation, and I'd bet the military guys would feel terrible if they knew, however chasing them or their unit down to pursue damages may not get you much. Probably should, but sadly I'm doubtful.
Best of luck,
