Mapping Network Drive via GP for Security Groups - Win Server 2016,

Hello,

I would like some help with mapping network drives for multiple users via group policy that are all in pre-organised security groups. 

I have seen a few posts/videos, documents on how to map via group policy but how do we apply it to specific security groups?

For example we have two security groups with:

HR - 10 users

MARKETING - 20+ users

I want it to apply to alone those groups, with those specific users inside those groups.

Thank you - *I have a looked a several posts, and other resources before posting.
