Vlad, what we should do is disarm the tanks. Deprive them of their main gun. That way they cannot shoot back and the field guns have a greater chance of lasting. And tap your Guard to remain unhit, then make your way back to the trench next turn, or even Leap up the valley to take cover until a refresh?
Vera-Kin will attempt that Agility roll, Ush. And when she reaches the tank, she will slash through its main cannon to render it harmless.
She will tap Balanced Guard, so that when the battle droids turn and fire on her, she will be able to fend off their shots. Swap it out after that.
