Unlike the Hellfire.....
More, the merrier
I have this Su-24M video (the 'NEBA' full russian version), from http://www.patricksaviation.com , in which there is some footage of PGMs, including missiles (Kh-25ML is my guess) as seen from the onboard thermal sight! The system does not seem to have an image lock capability, instead it is ground stabilised and constantly corrected by the WSO. Sometimes the targetting crosshairs seem to be way off the target, but still the weapons hit.
Some interesting shots of missile firing and KAB-500L releases there.
