I tend to agree with xv15. Scratch the bodyguard, and make the XV8s a tank hunter team. 1st with twin linked fusion blasters and target lock, 2nd fusion blaster and M pod and 2 gun drones, 3rd (Shas'vre) with twin linked M pods, plasma rifle, HW M tracker and HW target lock. Deep strike them as close to a tank as possible and blast away at the rear armour. Back the twin linked fusion guy up with missles and plasma shots into squads that are too close.
Or you could just turn it into a fire support squad, all with twin linked M pods, and pop them in and out of cover.
