Besides police & military, what is the purpose of government?

Hi! I usually don't vote republican, but in the name of understanding other people, I'd like to hear good-faith answers to an honest question.

Where I live, I mostly hear that conservatives want small government. Fine! But what do they want that government to do?

Aside from military and policing, what is the purpose of government, according to US conservatives in 2025?

I ask this in a genuine and non-argumentative way, and will happily listen to (and not argue with) replies. Thanks!
