Thinking about going Reserves, but have to re-class. My re-class options are 35F and 35M, what is the work environment like?

I am a 35f and its ok. The work enviroment depends on where you are stationed. In a tactial unit be ready for alot of physical security inspections and processing security clearance packets. At the stragetic level I do alot of reading and building powerpoints for briefings. But the clearance that you get is awesome for jobs in the civilian sector.

Both are excellent options. If you are an outgoing person with tons of initiative I would suggest 35M. If you are more reserved or have a type B personality you might be happier as a 35F. Have you considered dropping a packet for 35L? That job requires lots of writing and you must be a people person.

35F all depends on mission and where you are located. You can work at the company level, or all the way up to Corps. Tactical you will be doing lots of field analog training, Strategic you will be doing a lot of research and writing.
