Each job has a designation in that same way. The first digit denotes the branch of positon, the second denotes one of the specific jobs in that classification as well as does the phonetic character. All of the infantry positions are 11's, 12's, and 13's whereas research-based intelligence is all in the 90's. The farther from 11 the MOS is, the less that their job has to do with field work. Like, eleven-bravo (11-B) is standard infantry; twenty-five foxtrot (25-F) is a commu guy; ninety-seven echo (97-E) is an interrogator; and niney-six echo (96-E) is a code breaker.
