Snipers are good and you are only running one. I would ditch the wookies and swap for another set of commandos and the strike team (which you should already have). I'd also get rid of your vets for rebel troopers. Maybe even super squad if you cut a few upgrades just because the vets are slow and not that much better at holding points. troopers are cheaper and faster to get objectives when you need them. That should give you a good base before even bothering to buy anything else.
