I had a squad built at one point to utilize VAU, but it's a bit dated now. It was an Imperial variant of Billv15's Separatist 'San's Legacy' squad. Here's the link to my squad on bloo milk:

Also, if you use Thrawn, a combination of VAU and a Storm Commando can be lots of fun, because when you win init, you let the Storm Commando unload on somebody first, and then you fry them with VAU's lightning, hoping that they fail the activation save. Then you toss in Piett or some Evo Troopers or something like that to take advantage of the extra damage on already activated characters. Just have to be careful that you keep VAU well-protected until you're in a spot to do a ton of damage with him. With his 19 Defense and low-ish HP, he won't last long once you expose, unless you can manage to swap him around easily.
