First use the Elephant Artillery for counter-battery fire. Keep them as far back as you can. Have your regular Elephants screen the artillery ones. When all of the enemy's artillery is gone, move your elephants to one flank. Move them around and have the elephant artillery shoot down the army's line with enfillade fire. Have the regular elephants on the artillery elephant's flank. Watch for flaming arrows. Run your elephants back if under flaming fire to keep them from running amok. If your army is in trouble, run your elephants into the enemy's flank to rescue your army.
