Luna set up a shield as the tanks came into range to fire their own weapons, backed up by every unicorn capable of doing so. Other ponies took their positions, reloading the catapults, or firing their magic and ranged weapons at the Mareitanian soldiers not safely ensconced inside the tanks. The shield flashed as the first volley of explosives from the tanks crashed against it, and ponies were deafened by the explosions. The shield held though, although it was debatable how long it would against that kind of punishment.
