—Sergeant Dunn, "Carmencita"
After Juan Rico, Smith Alphard, Pat Leivy, and T. Azuma arrived an orbital base and saw the Rodger Young, the rookies soon met Sergeant Dunn, who asked them to check and maintain their "coffins". He also told the rookies to respect the etiquette and follow the rule since they are on board a Naval vessel.
During the Battle of Glendathu, Dunn lead the Wildcats to assault enemies. After spotting enemies' base, he asked the rest of the troopers cover him while he went into the enemies alone since the bombard squad was coming. However, most of the soldier went in after him.
