Just enlisted as a 94y for 3 years. Trying to get more information about the job. So what are your experiences or knowledge of this mos?

You picked a job without knowing what it entails?

I also have never heard of this MOS before.

Never heard of it. But, after looking it up, I would say that it is kith and kin to Biomedical Maintenance.....only your job will not be involving medical equipment.

I was an IFTE around the time of 9/11. After AIT I was stationed at Fort Irwin NTC. It's a ridiculously boring job. You will spend approx 9 months in AIT learning how to solder, test equipment with an oscilloscope, and how to repair multilayered circuit boards. Then you will learn how to connect "the box" to the test equipment and run various tests to determine the faults. "the box" is literally a steel box with several interconnected circuit boards inside. They come from weapons systems like the MLRS, you'll test the box, find the fault, remove the faulty card and replace it with a known good card. While at Ft Irwin I did nothing related to my job unless there was an NG/Res unit there on rotation and I spent my time reteaching people how to do their job. If you were considering Airborne or Air Assault forget it. They won't drop the $6million+ trailer you work in from a plane so jump school is not an option.
