Essentially, PoliceEMSActivity is a script in which is like a /onduty command, but on steroids. You can use /duty to toggle between being on duty and off duty. With this comes some awesome things too though. There are Blip-Tags people can toggle between if they are in multiple departments. Also, there are webhooks you can set up for each different department and send their clock-ins and clock-outs to when they toggle /duty or log off whilst on duty. There is also a /cops command so you can check to make sure all the people who are using /duty are actually on duty and in RTO (on your discord server voice channels I assume), then punish them accordingly if they use it for metagaming.
