This position is fine (in bold) but that wasn't what you said initially that caused my disagreement. I interpreted your statement below that one outcome is more probable than the other.
Yes, what I said before was that it was probably a generic term -- i.e.: a generic term doesn't explicitly exclude the possibility that it might be MIL-STD-1773.
Of course, that part which you quoted from me is essentially what my position 1 in my last post referred to:
"we do not know what J-20 is using apart from the possibility that is is an "advanced optic HSDB", because I believe that the acronym HSDB in this case is not referring to any specific MIL-STD or product, but rather used as a general term"
