Commanders are special characters of the game. They are the most efficient builders around so you can have him around with building advance stuff. You will also need to protect him from harm, other wise. He will die, if he dies. You will loose a match and every unit/factory/defense you have will be destroyed. Commanders, also have a powerful ION Beam, which can be fired through selecting [ALT+FIRE] in your command menu. This ION Beam Cannon deals alot of damage to enemy units, and considered dangerous against overpowered units also. You also start with him in every starting match. If you destroy the enemy's commander, then he will loose.
