The number of missing soldiers on the mission is too high, and they accepted orders from above bypassing him; he's not even aware of their whereabouts.
Now that matters here are resolved, there's no need to get too involved.
After Colonel Bai left, it was up to each leading soldier to explain daily arrangements to the students and clarify the preparations before the mission.
Major Sun was grateful that Colonel Bai wasn't old-fashioned. If it were other soldiers, communication might not be so smooth. He turned to Su Xiaocai and instructed, "Ahem, you'd better get a mecha first and make some modifications. Don't bring out your hoe-headed mecha."
Su Xiaocai frowned in disagreement: "My mecha is great; there are similar models online."
Even the online versions of the mecha look better than yours; at least they look new. Your mecha looks like a pile of moldy metal. It's indescribable.
Major Sun: "I know it's good, but it's embarrassing."
