I`ll have to go with Rosenadel, as far as i remember the Vindicare is the only shooty unit that can pick a model within the squad to shoot
Other SQUADS may do this by making more wounds than there are models in the targeted squad
if they do that, you can choose the target for the remaining wounds - or i may be wrong and you can only choose to have the remaining wounds fall on the 'sarge' of the squad
Hope that made any sense.
