Wild Weasel F4?
Yes, from what I remember, they flew in a pairs, an E and a G. The G or Geasel, had the EWO in the back seat to do the electronic wizardry and the E carried extra iron. They were refered to as a hunter killer team. I never flew the Weasel mission but had great respect for these guys. Their moto was "First in, last out". As I recall, G had a TISIO apparatus mounted on the leading edge of the left wing.
