AN/ALQ-144A and AN/ALQ-157M is an IR jammer, and effective against IR MANPADS. The newest Stingers are IR + UV to defeat this. This is the "disco ball".
I don't know how effective these are (I suspect the primary defense is route planning and flying low/fast), and no one who actually knows the effectiveness would be able to comment.
