Convert Master Chief to Enemy

Hey everyone; I’m trying to get a Master Chief enemy NPC. I’ve tried editing the LUA File only, but chaning the words Citizen to “Combine” didn’t work out so well. He dies in one hit.

Could someone convert http://www.garrysmod.org/downloads/?a=view&id=39945 to an enemy, with around 1.2x the health of normal combine, if you can easily?

Thanks!
