Hint has been given, help yourself. I'm not saying this because I'm a rude, grumpy old man, but because it would be faster to figure this out yourself.
Make a 32*32 map, place a footman and a peasant. Give the peasant the Command Aura and give the footman a custom aura based on the Command Aura, experiment and see what happens.
You have spent more time posting the second post than what it would take to make this sandbox map.
