When Han Li asked Ji Xinghe how many Red Stars he had obtained, at the headquarters of the Empire's Mountain of Gods War Zone, the Crown Prince was also asking how many Mecha had been destroyed under his command in today's battle.
You have to inquire and calculate; since warfare is essentially about resources, how could one possibly avoid accounting?
Relevant data was continuously being collected, and when the Crown Prince inquired, the answer was immediately clarified.
"The Anti-Xinghe Legion's first, third, and fourth Mech Corps have been completely wiped out. The fifth Mech Corps has lost more than half, the sixth Mech Corps has just entered the battle, and the seventh Mech Corps is on the way for reinforcements, expected to arrive at the battlefield within twenty minutes. The eighth and ninth Mech Corps just set out, expected to reach the battlefield within forty minutes. The second Mech Corps is estimated to take an hour."
