| The Navy refers to both O-7s and O-8s as "Rear Admirals". Technically the O-7 is "Rear Admiral (Lower Half)" and O-8 is Rear Admiral (Upper Half). Keep this difference in mind when rank-ordering officers in these two grades. When writing refer to them as " Rear Admiral;" when speaking they are both "Admiral" |
