I'll Join the Fight! - S1.E3

Mako, who is revealed to be a childhood friend of Saori, joins the others on the tank, which soon comes across a perilous bridge which Hana has trouble navigating. After a hit from enemy fire knocks Hana unconscious, Mako takes over as driver and manages to safely navigate to the middle of the bridge. There, they manage to find perfect cover from enemy fire whilst Yukari takes out the enemy tanks, securing victory for Miho's team. Whilst celebrating their victory, the team decides that Miho should be the commander, with the roles of radio operator, gunner, driver and loader assigned to Saori, Hana, Mako and Yukari respectively, before going shopping for things to make the tank more comfortable. Later, the students are informed of an upcoming friendly battle against St. Gloria's Girls Academy, of which Miho is assigned as the commander for the school's team.
