What counts as a Technical Certification? Does it have to be in your MOS field or can you pick any Certification?

In the IT world, you would need to pick a certification that will benefit you. You don't want to certify as a Project Management Professional, if you're going to work as a Network or Systems Administrator. For those you would need Network+ and probably CCNA. If you're3 going to be a programmer, then you would need to certify in a programming language. If you want to work in Aviation then you will need you Air-frame and Power Plant Certification, and or your FAA Cert in Avionics
