Mr. Powers. That's correct, yes.
Mr. Jenner. And it included the classes of uses of radar and other aircraft warning devices?
Mr. Powers. Yes, sir.
Mr. Jenner. Were you awarded the—what is known as the M.O.S., Military Occupation Specialty?
Mr. Powers. Yes; we were. I believe coming out of—excuse me—coming out of Jacksonville, Fla., we were given a general M.O.S. of 6700, and then after—
Mr. Jenner. Explain what that means to me.
Mr. Powers. M.O.S. is a Military Occupational Specialty, and all it does is categorize you as to what you are going to fall in when they issue you orders; and 6700 is aircraft, as I understand; my memory may be somewhat faded or dim.
And when we did come out of Keesler, then we were added the additional digit of 47 which would make us a ground—I better not say "ground control," radar operator for—as a guess, I would call it an early warning system.
Mr. Jenner. And how long did you boys remain at Keesler?
Mr. Powers. Exact dates would be from 4 May to 4 June 1957, is when we picked up our orders to go to California.
