@Pawp I’ll defer to folks like
@Totentanz with CA experience for that career path.
In the intelligence MOS’ you really break into two categories – analysis and collection. Both tracks produce intelligence but generate it in different ways.
The analysts (35F, 35G, 35S, 35N, 35P) are categorized by the intelligence disciplines – all source, signals, and geospatial. They learn to utilize advanced computer systems, sometimes at a desk in a hard-stand building, sometimes on the back of a HMMWV – to turn data into intelligence (called production, exploitation, and dissemination – or PED). They then turn that intelligence into reporting – serialized (in a preset format in a time-sensitive manner) or more free-form presentations. In all cases they need to be able to assess the intelligence and deliver products that answer intelligence requirements. You will do a lot of reading, a lot of writing, a fair amount of briefing, and hopefully a lot of critical thinking and analysis. You’ll need to learn and employ the skills of a Soldier but most of your work will be behind a desk – in the field or in garrison. Some signals and geospatial analysts serve on aircrews or in specialized ground units that collect and turn data into analysis/reporting very quickly.
The collectors (35M, 35L) conduct military source operations (MSO) focused by the intelligence disciplines human intelligence (HUMINT) and counterintelligence (CI). Both spot, assess, and recruit sources – run, then terminate the sources. The difference is the purpose of the source. HUMINT collectors recruit and run sources to find out things the CDR needs to know to target the enemy, CI runs sources to find out/combat what the enemy is trying to do to us. CI agents also run investigations on internal threats. Collectors work in the field (to spot, assess, recruit, and run sources) and in the TOC. They have to interact with the population to do their job – but it has to be planned carefully so there is a significantly higher ratio of planning work to field work. Collectors report the information/intelligence they gain running a source in very detailed serialized reporting. A collector needs to be good at interacting with people, good at planning, and excellent at writing.
The new Cyber MOS is not an intelligence discipline but the work is very close in general terms to what you would do as a strategic SIGINT Soldier.
The 35T MOS is an intelligence Soldier, but they maintain the networks and systems MI Soldiers employ.
