How do you kill the Arbiter in halo wars?

[jetpacks and pirates]

In the online mode he's pretty much unstoppable fully upgraded unless you have grizzly tanks but I always go covenant. what are some good units to kill the Arbiter.

id say the power drain or the old fashion way...... over populating ur forces and beating his a$$ in

LAWL XD

If you go UNSC and use the power drain he can not use his special attacks making him a hell of alot easier to kill.
