Who differed from militias in that it was made up of mostly full time?

The group that differed from militias by being composed mostly of full-time members is known as a standing army. Unlike militias, which are typically made up of part-time volunteers who are called upon in times of need, a standing army consists of professional soldiers who are permanently enlisted and trained for military service. This professional force is maintained during peacetime and can be deployed as needed, providing a more stable and ready military capability.
