Sound didn’t travel in space. The explosion of a starship being hit by missile would otherwise be loud enough to damage everyone’s hearing. And so Zheng didn’t know everything happening outside. He walked off the shuttle.
Troopers were running around in panic outside the shuttle. Their eyes expressed an emotion of fear. Zheng noticed that most of the troopers present were the ones who came along with the military higher ups and never actually entered a battlefield, so they appeared inexperienced in an emergency situation in comparison to the veterans. They were only following orders from their superiors. These troopers he saw were commanded by some veteran sergeants and were in a standoff with another group. The other group had their own sergeants and even lieutenants. It seemed like these were the officers that came with the backup.
