Anyway to fix combine suicide running into enemies?

Hello everybody, I haven’t posted here in years and this question isn’t really that great. But it’s been bothering me that combine npc’s don’t fire from a distance like the citizen npc’s. Instead they stare at enemies, run up to them and only fire when they are practically touching whatever they are attacking. I’ve looked all over but addons that claim to improve AI don’t really do much. Are there any console commands or addons that increase the view distance of combine? Or solve whatever problem this is?

Thanks for your time guys.
