With 5 tanks found, the Tankery class split into teams and stage their first mock battle.

As Miho once again uses the radio interceptor to lure the rest of Saunders away, the Duck Team manage to find Alisa's tank and lures it into an ambush by the other Ooarai tanks. After learning the truth about the radio interception, Saunders' commander Kay sends an equal number of tanks to pursue Ooarai as they chase after Alisa, taking out both the Rabbit and Duck teams. Despite the grim situation, Miho calms her nerves and urges her teammates not to give up. Climbing up to the top of the ridge, the Anglerfish Team manage to take out Alisa's tank before they are taken out themselves, winning the match. After Kay commends Miho on her victory and takes her leave, Mako receives a call that her grandmother has been taken into hospital. Hearing about this, Maho allows Mako and Saori to take her helicopter back to Ooarai to see her.
