Baka - insult in Japanese, "idiot".
Drama - <I can't think out a good definition here>
-heika - Japanese honorative used for the top rank officer, emperor; rarely, prince or other imperial royalty
IKS - Imperial Kusari Ship
IKT - Imperial Kusari Transport
Ryokai - yes sir; roger
-san, -sama - Japanese honoratives used for the higher rank officers or older people
-senpai/-sempai - Japanese pseudo-honorative used for overall higher rank officer; literally "boss"
-kakka - Japanese honorative rarely used, but still present, for the Shogun.
