Sort of true and sort of not true? While PJs have assignments in AFSOC and in support of SOCOM directly in those assignments, Personnel Recovery is a direct tenet of SOF (under ‘direct action’). All those assignments should be considered ‘SOF’ assignments as well, even though it’s not for AFSOC.
For instance- the last two Silver Star winners (Brunetto and Fisher) were both PJs assigned to SOF mission sets working at rescue units (38/58, respectively).
