I don't fight because I want to. I fight because I have no other choice.

Mr. McKenna served as a Security Police Officer (AFSC 3P031) and Security Specialist (AFSC 81130) in the United States Air Force, where he was entrusted with the protection of some of the nation’s most sensitive assets and missions. His duties included providing security for high-profile operations such as Air Force One, Air Force One Bravo (National Emergency Airborne Command Post – “Nightwatch”), AWACS, Cobra Ball, Landshark, and other high-priority aircraft and resources. These assignments required advanced operational awareness, strict adherence to security protocols, and absolute discretion.

Mr. McKenna also participated in the Emergency Services Team (EST), the Air Force’s equivalent of a tactical response or SWAT-style unit. In this capacity, he was involved in high-risk response operations, base defense, and special security functions, which laid the groundwork for his later work in private investigation services.

Throughout his military service, he supervised and performed a wide range of security operations, including weapon systems security, air base ground defense, and the protection of personnel, aircraft, equipment, and facilities. He also engaged in resource management and critical asset protection, armament and equipment training, pass and registration operations, and information security for classified materials.

Specialized training in critical areas for both military and investigative support was a significant part of Mr. McKenna’s experience. This included legal considerations and use of force, deadly force policy, confrontation management, and physical apprehension techniques. He gained proficiency in antiterrorism principles, threat assessment, and the execution of Air Base Ground Defense (ABGD) concepts, alongside systems security operations and resource protection, nuclear, biological, and chemical (NBC) defense, military operations in urban terrain (MOUT), and the law of land warfare.

His weapons and tactical training encompassed the operation, maintenance, inspection, and deployment of various weapons systems, as well as live-fire range operations, preventive maintenance, and safety compliance. He received instruction in individual and squad-level tactics, patrolling, communications, navigation, and coordinated response operations.

This comprehensive military background laid the foundation for Mr. McKenna’s investigative career, instilling discipline, attention to detail, legal awareness, and an uncompromising standard for accuracy and documentation. These principles continue to guide Sentinel Associates in every investigation and litigation support service performed today.
