Combine balls

After playing a bit of HL2, I noticed Combine in Garry’s Mod won’t shoot combine balls. How do I get them to shoot them? And also, is there a way to increase AI aiming?

I dunno…I think its for the fact that NPC’s NEVER use secondary attacks…Also did they realy have to call them combine balls
