Now let us assume the AFV would be CE, i.e. has a vulnerable Crew. Even if there would be other units in the same Location, you could now per the A14.2 Exception select that vulnerable Crew without having to roll Random Selection.
If the said CE AFV would be Concealed, though, then Random Selection between the Concealed units (all of them treated as one option) and non-concealed units would apply and you cannot immediately select the CE concealed AFV (even if you can conclude it must be one).
If the said CE AFV and all other units in the hex are Concealed, then I am not sure:
You'd probably have to specify the number of elegible targets but I think you do not need to state whether the Concealed AFV is CE or not. As a consequence, I think that you cannot specifically select the CE AFV but only hit it via the normal Random Selection process.
Thoughts?
