Milton Said:

Which branch of the military is best for intelligence officer positions?

We Answered:

All branches have very good intelligence programs.

One thing you need to consider is that the Army probably has the most seats available in intelligence as they are the biggest branch. Other branches may not be able to guarantee you any specific job.

"considering the Air Force since I know it has higher intelligence entry requirements and I would think is more strategy/tactics based than combat based"

This is wrong. The Air Force has higher requirements for one simple fact: they are small. They are about 1/3 the size of the Army and thus do not have the recruiting demand.
Also, that thing about strategy/tactics versus combat based intelligence is misguided.

In summary, all the branches have about the same level of training; in fact many people from all branches train at the Army's Fort Huachuca. So to make your decision you need to check out what types of intelligence each branch offers, then weigh the benefits and availability of the jobs you want.
