Verba MANPADS also has thermal sight.
But terrorists don't have that. And having it turned on all the time carrying a MANPADS on your shoulder 24 7 is too heavy and uses up too much battery when an airstrike takes only a few seconds from start to finish.
Speaking of a few seconds for an airstrike, Su-24 has crosswind sensor. The computer takes in all kinds of info like GPS, wind speed, wind direction, air pressure, humidity and all that and computes the fire solution. Even if there is wind it don't blow big bombs off course too much in only a second or two.
