CMSgt Lockhart initially entered the Air Force in October 1992 as an Explosive Ordnance Disposal (EOD) Technician. During the 23 years of service he has accomplished a myriad of assignments with responsibilities at the tactical, operational, and strategic levels of the Air Force. Currently stationed at Davis-Monthan AFB, Arizona, he leads an EOD team that is responsible for providing military EOD capability to the base and surrounding Southern Arizona. Outside of the Continental United States, he has completed multiple deployments across Middle-East Asia, to include Iraq and Afghanistan, ranging from team leader to Air Force Central Command-Forward EOD Functional Area Manager.

Over the years, he has demonstrated a drive to align himself into positions to better enable support of the EOD Career Field and ensure maximum operational readiness and support for all bomb disposal technicians. Notably, he accomplished assignments as Non-Commissioned Officer in Charge Curriculum and Instructional Standards Office, Naval School EOD, and Air Force EOD Operations and Training Program Manager, Air Force Civil Engineer Center. Both of these assignments required him to have responsibilities for the Air Force and Joint capability, as a whole.

He feels that effective training and the best EOD resources are critical to operational readiness and strength. With that, his focus is to best organize, train and equip our capabilities.

Additionally, through his experiences with his public safety bomb squad partners in Arizona and previous assignments, he has recognized the importance developing and maintaining close relationships between the military and civilian technicians. He has seen that these relationships have improved capability for both sides and feels that it can continue to evolve nationally to have exponential positive impacts across the country.
