The CAG is repeatedly addressed as "Sir". A female military officer is supposed to be addressed as "Ma'am".
At one point in the game the CAG puts Maniac in charge of the Black Widows squadron and he says "After all these years, to finally have my own squadron." However this is not the first time Maniac has had his own squadron, in Wing Commander II: Special Operations 2 he is in command of the Wild Eagles squadron, test pilots of the Morningstar prototype fighters.
