Summary
Analysis
Soon after Ringer’s arrival, Zombie’s squad starts to move up the ranks. Their one weakness compared to other squads is marksmanship, despite Ringer and Poundcake’s skill. Ringer trains Zombie on the shooting range. She gives him advice about seeing his M16 as an extension of himself. Following her advice, he improves his aim.
This passage shows how Zombie improves himself by working with Ringer. Unlike Cassie, Zombie accepts help from people around him, and this not only improves his skills but also helps him to begin building relationships with his fellow squad mates.
