I'm not sure what you're referring to. Is it a beacon? If so, what color and what are the symbols on it?
My 2 cents:
It doesn't seem ambiguous to me; if you eliminate the opponent, you never initiate the skill test and you don't spend a TU [unless I'm missing something and it takes 1 TU to break a beacon]. I mean look at the icon... there are no active sheilds of any type, thus there is no test.
