To avoid bringing a year old topic back to life - in a situation such as the Truman scandal, or similar, how would you advise a future nuke handle the problem?
Specifically if you were on a sub, underway, and the immediate chain of command supported actions that threatened integrity, how could a lowly E-4/5 keep their nose clean while avoiding living hell during that deployment or future deployments by being labeled a snitch?
The link to the cheating topic really got me thinking as to how to handle a situation. While I would like to think I could simply "act" like I was cheating by studying and passing the tests anyway, if the tests were on information not presented or something along those lines I can think of no other option than failing and being brought to mast or other measures.
Perhaps a discussion of potential actions for the "Future Sailors" could help avoid career ending mistakes in the future.
First, we don't know what the OP's problem really is...other than he was fired. He'll have to deal with what his DD-214 says after his potential future employers read it, what his security background reveals, and what his references maybe say about him. No one here can tell you what all the nuclear/non-nuclear ex-Navy nuke employers will do with one in the vague case above.
Second, the punishment for significant lapses in integrity are fairly "nuclear universal". There was nothing to "discuss" with the Truman, or any other public event. You intentionally skirt the rules as a nuclear and you're a non-nuclear. Simple.
Finally, study. You study to get qualified/licensed, you have to study for requal/continuous training exams, you have to study for your next bigger qualification (e.g., EWS). You have to know your plant. The Boat/Ships that TRY to game the system usually get caught by ORSE grades. So, before policing what you "think" might be going on around you, just make sure that if you're questioned YOU can say that YOU did the right thing. I've never seen anyone fired from the Navy for failing a continuous training exam. If you feel strongly that someone is going on wrong around you...there is ALWAYS a way to make your point heard to the right person...even anonymously.
Good luck.
