I'm stuck!! I have no way of reinforcing my troops and insufficient troops to break throught the lines, each bridge seems protected by and AT-AT+ other bits and bobs
I can't seem to find a third way in, the whole map seems scatered with 4-8 AT-ST patrols which whilst I can handle running into one of the the artillery bombardment tends to finish me off an even if I survive that I'm still stuck the wrong side of the bridge!!!!

I don't understand what I am expected to do, any ideas??????
