What are these on the F/A-18F's wingtips? At 5:34, former TOPGUN instructor Cdr E. Vincent Aiello (the narrator) says 


  Looks like you've got [I can't decipher] Xes.



What words was he speaking?
Is he identifying the missile-looking object marked by my red arrow below?
He says:


  Looks like you've got some AIM 9Xs on the wings


Yes, the AIM 9 is a commonly carried short range air-to-air missile, with the 9X being a particular variant.
