Web site makes it easy for reservists to volunteer for critical positions Published June 24, 2010 By Staff Report 419th Fighter Wing Hill Air Force Base, Utah -- Reserve and guard personnel can now apply online to fill a wide variety of critical positions throughout the Department of Defense. The Personnel Force Innovation Program Web site lists crucial DoD manpower vacancies and serves as a one-stop shop for reserve or guard personnel who want to volunteer for the positions. The PFI site is located at: http://pfi.dod.mil/. Through the PFI program, reserve component personnel perform the volunteer duty on a reimbursable and fee-for-service basis, which is more cost-effective than hiring civilian employees or contractor support personnel for the temporary positions. PFI vacancies are filled for one to three years at a time.
