Ok,here is how the story goes....
We do setup,and play turn one.Bikes speed out of LOS.
Each time 3 land speeders arrive,they do so by destroying one tank .So after 3 units of 3 take 3 tanks down-I´m left with 5 tanks.After that ,I can surely kill some,but not all 10 land speeders.You have to see it to understand.The point is that I'm forced to move,to get LOS on them,and each time i kill one speeder,he kills one tank.Some of the tanks will get stunned,etc....
