Tango,
I wasn't a "crow". I was a pilot.
Initially I joined the 343 SRS and the patch had that sleepy raven on it. The "front end" crew.. pilots and navs... were in the same squadron as the "back end" crews, the Electronic Warfare Officers. The Security Service personnel, were, of course, in a completely different squadron. Those guys were extremely sharp.
As the mission and number of crews expanded, a decision was made to split the squadron into two different squadrons, the 343 SRS and the 38th SRS. The "crows" or Ravens as they more formally called themselves remained in the 343rd. (They hated being called "crows".. so of course, that's all we ever called them.
) The pilots and navs went to the new squadron, the 38th.
Interestingly, one of the primary reasons for the switch was to create more command opportunities for non-pilot officers (ie: Navs and EWO's). There was a big brouhaha that these guys were not getting a fair shake in the promotion game due to the fact that flying squadrons/wings were always commanded by pilots. So, their opportunities to show their stuff and shine their resume were limited. I believe that they had a case.
In any event, the 343SRS became the dream assignment for EWO's with command aspirations.
As to the period I mentioned (without divulging classifed info) my crew flew a large number of those sorties. We volunteered for them; they were longer (built flying time faster so you timed out for the month earlier and got more days off) and they had receiver refuelings (the pilots always enjoyed that).
Nearly all the news "combat reports" that made the mainstream media concerning the Chinese incursion into North Viet Nam were generated from information collected by the RC-135's. We were "bylined" as "sources close to the battle zone". I often read summaries of intel my crew picked up in the newspapers about a week after the mission.
As I said, the Chinese were poorly led, poorly equipped and tactically deficient. It was funny listening to them (through our translators) scream at each other for their screwups.
