Blastcore, JSRS packages, Enhanced Movement, and ShackTac UI are not required but are useful.

Note that Task Force Radio requires the Teamspeak plugin to be installed. Most people will find the installer at:
C:\Program Files (x86)\Steam\steamapps\common\Arma 3 \!Workshop\@task_force_radio\teamspeak
(don’t take the spacing here as gospel)
Your Steam library might be different, but if it is, you probably know where to look already.
