I have involved in setting these up and selecting members to be at these luncheons/photo ops/dinners. Usually you'll have the opportunity to ask a question or two during the lunch...sometimes prompted...but getting one on one face-time may, or may not, be a possibility. You are going to have to be on the lookout for your chance...that or ask for a moment with the Admiral from one of his aides. Keep in mind that about every minute of the Admiral's visit will be on a tight schedule and is usually directed by the base's Public Affairs office.
Next, you need to put together a 15-30 second commercial about yourself, much the same as though you were job hunting and had only a few seconds with someone in the hiring chain to sell yourself. Include all of your military accomplishments, awards, distinguishing moments like doing well on training or volunteer events you led or took part in; end it with you asking for his recommendation to the officer academy.
You want to look exceptionally sharp in both your appearance and speech. Be clear, concise, personable, professional and make sure whatever you wish to ask or talk about is practiced and polished.
The Admiral is just a person so don't be nervous around him, the worst that can happen is he says no and you haven't lost anything. This is a rare window of opportunity so insure you are prepared and confident. Good Luck!
