Army Techniques Publication ATP 4-02.2 provides doctrine and techniques for conducting medical evacuation and medical regulating operations. Medical evacuation encompasses both the evacuation of Soldiers from the point of injury (POI) or wounding to a medical treatment facility (MTF) staffed and equipped to provide essential care in theater and further evacuation from the theater to provide definitive, rehabilitative, and convalescent care in the continental United States (CONUS) and the movement of patients between MTFs or to staging facilities. Medical evacuation entails the provision of en route medical care; supports the joint health service support system; and links the continuum of care. In addition, it discusses the difference between medical evacuation and casualty evacuation (CASEVAC), as well as coordination requirements for and the use of nonmedical transportation assets to accomplish the CASEVAC mission. The principle audience for this publication is all medical commanders and their staffs, command surgeons, and nonmedical commanders involved in medical evacuation operations. Army Techniques Publication 4-02.2 contains seven chapters and two appendixes. Chapter 1 provides a brief overview of the Army Health System (AHS) and how the medical function of medical evacuation relates to the principles of AHS. It discusses the purpose, primary task, and attributes of the Army medical evacuation system. It also defines the differences between medical evacuation and casualty evacuation. Chapter 2 discusses the factors that establish the evacuation policy and the impact of the evacuation policy on AHS support. Chapter 3 describes the mission, function and capabilities of medical evacuation units and elements as specified in the unit's table of organization and equipment. It also discusses the mission command headquarters to which they are assigned. Chapter 4 provides insight and considerations into developing the operational and tactical medical evacuation plan that supports the combatant commander's (CCDR's) mission. This chapter also provides descriptions of medical evacuation tools that are essential to the medical evacuation plan. Chapter 5 discusses the employment of medical evacuation resources and the coordination and synchronization required to effectively execute medical evacuation operations. This includes the medical evacuation request process, consideration for medical evacuation missions, and support planning considerations. Chapter 6 addresses medical evacuation in specific environments or under special circumstances. Chapter 7 describes the medical regulation system designed to ensure the efficient and safe movement of regulated patients to the appropriate MTF by the most effective means. It also discusses the multi-Service responsibility and assets used to conduct this mission. Appendix A provides a summary of the Geneva Conventions and medical evacuation. Appendix B provides an example of a medical evacuation plan as part of an operations order.
