In any Part121 operation it's pretty much useless. I still would include it in my total time but be ready to explain it as I have had to for previous employers. Being on the C-5 for a few years has given me a bunch of "Other" as well. Remember not every 121 carrier is full of ex-military types so if they are looking at your times be ready to explain what it means. In the Herc though I wouldn't think you should have much anyways.
