What advice do you have for an 11B thinking of reclassifying to 35M?

I'd take a look at what you want to do outside the Army. Switching from 11B to anything else is a good idea when it comes to marketable skills. 35Ms are a lot more specialized and is a good route if you want to, say, be a cop. Those interrogation skills will come in handy. However, if you want a good solid government job, look into 35N or 35F. Geoint and all source are both multi-faceted paths and give you a lot of opportunities on the outside. Definitely look at your next steps outside the Army world.

I'm biased toward 35F. They would have legit mission work wherever hey are. M's probably the least of the 35's when they are not down range. Each 35 series has their own set of technical skills, but Imagery, Signals and All Source seem to have the best civilian options open to them.

Regardless, all 35's are better off in an INTEL unit than they are stuck in a non Intel unit S2.

If you like working with 2faced back stabbing Hippocrates, reclass and go 35M. 11B/13B is where it’s at for schools, promotion and progression. Being in the intelligence field you have to be willing to embrace political nonsense as well as those who feel they need to defend the MOS as if they are some elite MOS god. 35M is one of the worst MOS I had and if I could I go back combat arms without a doubt. If your not willing to work in DC/Virginia or Maryland area after you serve as a an intelligence MOS, or plan on working as a civilian for the same MOS as an instructor, the intel field is garbage.
