The instructor makes a huge difference.

As it is currently practiced, doctrine prevents the Sgt. without a degree- but with years of experience training polic officers in Iraq or Afghanistan, from leading or designing the sort of training that is actually relevant to our military's needs. However, the PhD with no recent field experience in the region is qualified. In fact, I am aware of an instructor meeting that description in the system right now that has spent a career studying Ireland, has no military experience, and is teaching an Islam-specific knowledge course.

The USMC CAOCL says (and I agree): "Instead of generalist historians, religion specialists, and journalists, younger personnel who combined recent operational experience with academic study, site visits, and debriefing of returning units conducted the training. In this respect, cultural trainers have been working to shorten the lessonslearned feedback loop from deployment to
deployment…he or she must be a Soldier or Marine who has recently deployed operationally to the AO in a job requiring ongoing interaction with the indigenous population--the division combat operations center watch officer from OIF-I will not do. MOS is not important here; interaction with Iraqis on a regular basis is." (“Advances in Predeployment Culture Training: The U.S. Marine Corps Approach”, Barak Salmoni and Paula Holmes-Eber)
