Persuing Non-Military Professional Certifications: What's your viewpoint?

The military doesn't own the book on job related training. I know plenty of commo folks who have Microsoft & Cisco certifications that apply to both their civilian and military careers. I also know some senior folks with PMP certifications for their civilian jobs.

I feel that this is dependant on the job.  I actually hold a Medical Surgical Nursing Certification.  Guess what? I am a nurse.  It helps show professionalism and knowledge.  It is a civilian certification, I paid for it out of pocket, took the test on my own time, but the AF will benefit from it until I get out.  In the case of Nursing, it DID help the career.... to make Major, it is almost an expectation that nurses hold a certification and have a Master's degree (although they SAY it is optional), when all your competition has it, it becomes a requirement. 

The most valued certifications in corporate america outside of a specific niche career would be a high level LEAN-Six Sigma Certfication or PMP.
These are applicable in ANY & EVERY Industry. WIth a Black Belt Lean Six Sigma or Master Blackbelt you could immediately transition to a very well paying career easily approaching or exceeding 6 figures. Within a few years you will comfortably be making in the 6 figures. The GI Bill will pay for it. I highly recommend it.
