I am busy memorizing the Big 4. I had a question though regarding the memorization and recitation of the rank structure. . .What exactly is it we should be memorizing? Once at OCS, is it simply reciting the rank structure and rank insignia from Ensign/2nd Lieutentant to Admiral/General (ie, "Ensign, one gold bar; LTJG, one silver bar; Lieutenant, two silver bars; etc.")? Thank you for the advice/suggestions. You all are great.
