So, Stephen went to his older brother, and his brother said that you need to be ranked in an army before you go into battle.

Stephen is moved up by 8, a Lieutenant Colonel.Then on Day 2, it says that Jessica is moved to First Sergeant, and Anna moved 2 higher than that, a First Lieutenant, and Clark is moved 4 below Anna to Corporal.
