Captain is the standard spelling XD

And it wouldn't be Cadet (Only people at military Academies are cadets), it would be Navy ranks because "medics" for the Marines are really Navy Corpsman and are referred to as "Corpsman", so HR (E-1), HA (E-2), HN (E-3), HM3 (E-4), HM2 (E-5), HM1 (E-6), HMC (E-7), HMCS (E-8), HMCM (E-9)
