I said IF.
I have not been able to do much research on the matter. I can start doing that now. I am fine with having to figure out what the ability is. But if a certain function of SF troops is already widely known, I do not feel bad for requesting that information.
Also, I was forced to recruit from a variety of SF RCs already. And if their ability is gone, I do not want to start trying to figure out an ability that no longer exists.
