Hello, J. -- (welcome)
Re Dolbejeff, he's on several Army rosters as "Dolbejeff, Basile J." but no Dolbejeff pops up on any internet search routines, anywhere. Sorry.
Re McJunkin, Davey Silk is around here sometimes and may be able to help. I forget whether he found him or was still looking for him.
Re Corbett, there are zillions of Corbetts around, but one internet search coughed up 6 "Charles M" returns:

Re helicopter crews and literacy, I am making a superhuman effort to resist pulling the trigger on about a hundred different wisecracks that are washing over me in waves...
Best,
