There is a huge variety to choose from and in the past few years the Harrier Force were able to really mix their weapon loads giving them unprecedented flexibility. They can operate (and often did in Afghanistan) with the Digital Joint Recce Pod on the centreline and a Sniper pod on the left shoulder pylon. The right shoulder had the thin aerodynamic 'fillet' thing attached. On the wings you could take your pick, but they wouldn't fly with Sidewinders (no air threat), but they would have the BOL launchers on the air-air pylons and sometimes also on the outboards. The enhanced Paveway 2 was widely used as was the Paveway IV towards the end of their deployment. There are quite a few pics on Google Images (type in Harrier Afghanistan or something similar), but i include a picture below. They often had a mixed combat load of EPWY 2's and CRV-7 rockets outboard and 2 fuel tanks inboard plus Sniper or Litening 3 pod. Good luck and enjoy. They even had an assymetric Paveway 3 loadout, balanced with BL755 on the other wing!
