No, they are providing supporting, cover, and harassing fire. Use whatever term you would like. The big problem is the word 'sniping'. It is a deliberate art of controlled-accurate-deadly fire (if you are shooting at human targets, remember, there is also sniping at vehicels and other hardened objects for example).
I guess you can say the BHD snipers were just "shooting at" targets. Actually, I have to see that movie again to give you any more info.
We have to differ from "shooting at" and actually "sniping". I tried to use as simple terms as possible so everyone can understand. Did it work?
