As battle engagements go, the casualty rate of that first wave of three thousand mechas was horrendous.
It was well within the category of a massacre.
Except for the most well trained special forces, most military units would break as soon as they suffered such a mind blowing casualty rate.
It would be logical for students to break and run at casualty rates far below that of the standard in adult soldiers.
However, it wasn't the case for students entering that particular set up.
Instead of breaking and running at fifty percent casualty, these students actually continued to charge into the battlefield until they were over 90 percent committed!
To an extent, one could probably lay the blame of why these glorious National Mecha Pilot Academy students continued to charge in blindly into Sheera's killing zone and to their deaths, on the terrain.
