This one came up.
Unit has Split Fire (e.g. Deathwing Terminator Squad).
Split fire rule is on p42 and states that the unit makes a Ld test. If passed nominate 1 model to shoot. That model immediatly makes a shooting attack. After that attack has been resolved, resolve the shooting from the rest of the unit.
So, could the singe model fire at a transport, and assuming it was destroyed can the rest of the squad now fire on the unit that had been inside (and is now presumably disembarked or sitting in the crater)?
I feel they could as the first model's shooting is conmpletely resolved before the rest of the unit shoots.
At what point must the target be declared? Before any of the models shoot, or just before the particular elements (i.e. 1 model vs squad)?
