Well, I have tried, but to no avail, looked at a a few different templates that were give, so here's what I got, this was just a test run, but did not work.
Agency:
Regions:
Backup:
Also, I am potato at adding add on vehicles, hence the "bpsp1, bpsp 2." They are in the DispatchWorks mod, which I used to add vehicles and change their names.
Edit: I have found out that my units will ambiently spawn, however will not respond when backup is requested.
