Hello Dave , I will try to answer your questions :
1. Usually the IRIS-T are carried on stations 2 and 8 (close to the wingtips), instead of the AIM-9s, mostly combined with AIM-120 AMRAAMs.
Note that the IRIS-T are only carried by the F-16C/D versions Block52+ and Block52+ ADV, the earlier (Block 30 and Block 50, of the Hellenic Air Force), cannot carry them.
2. Hellenic F-16s don't have the HTS (HARM Targeting system)
3. The SEAD squadrons don't carry the LANTIRN pods, they are dedicated to the SEAD role.
4. Hellenic F-16s don't carry the LITENING pod, only the LANTIRN ones.
Feel free to ask anything you like .
I have built many Hellenic F-16s http://www.aircraftresourcecenter.com/Gal10/9701-9800/gal9768-F-16-Zorotheos/00.shtm
Currently I'm also working on Hellenic F-16C Block52+ which participated at the RED FLAG in 2008 scoring 18 victories against the Aggressors, using mostly the IRIS-T.
