"Incoming." The System stated loudly through the System Channel which prompted the Orc Artillery Company to ready their fingers on the trigger and shells to be discarded and reloaded. When there was no movement for about five minutes, Moloch had already informed Orc General Nubwort to change the type of artillery shells they had been using.
What they had initially used was the smaller 75mm artillery calibre in order to save the better ammunition on their howitzers for the later fights. Now, Moloch had called on them to switch to the chemical shells as he predicted that the demon army would be sending in their armoured knights to counter the explosive rounds.
"Use them before the mages appear and wipe the chemicals off," Moloch told them and the Orcs manning the howitzers had already equipped themselves with sufficient safety gear in case the chemical shells malfunctioned or backfired on them.
