That is funny because I double-dipped too. After I got out, my employer paid full tuition for my Master's degree and I was still eligible for the GI Bill (Montgomery). It was a nice part time job!
I worked on the MK 19 and the MK 27 but was always more of a voice communications and atmosphere monitoring guy than navigation. But, I was an instructor before I got out and I taught pretty much everything, including the Mk 19 - the shorter 4 week school, not the long 19 week version. We still had some training videos dubbed from film that I am sure you would recognize.
