CASEVAC: movement by nonmedical means
CASEVAC stands for Casualty Evacuation and means moving wounded, injured or ill people by means not designated for medical evacuation. Vehicles, aircraft or boats may take the person from the point of injury to a transfer point or treatment facility; sections that vehicles cannot reach may first require movement by litter bearers. For isolated personnel, CASEVAC therefore connects actual pickup with the onward journey towards care. The care possible during that journey depends on personnel, equipment and transport conditions.
During recovery, forces must first be able to reach the isolated person, authenticate their identity and take charge of them. They must then also negotiate the route to the recovery platform. A transport vehicle on a road, for example, does not solve access to an injured person inside a building or in difficult terrain.
CASEVAC and MEDEVAC
MEDEVAC means medically supported movement using assets designated for that purpose. Personnel and equipment enable the care required during transport. NATO uses CASEVAC in a narrower sense: it means movement without medical supervision and without employing dedicated or designated medical capabilities. The person is taken to the point where they enter the medical support system.
The US Army places particular emphasis on the platform: CASEVAC uses nonmedical vehicles or aircraft. For a planned operation, medical personnel, appropriately trained soldiers and supplies may be assigned to them. En route care is then possible to the extent that the personnel, equipment and available working space allow it. In Army usage, the presence of a medic alone does not turn a nonmedical platform into MEDEVAC.
Who accompanies the journey, can the person be reached and observed during movement, and does the equipment meet their care needs? A helicopter can also be a CASEVAC platform. Its ability to fly says nothing about medical staffing or whether it can pick the person up at their location. Conversely, a ground vehicle designated for medical evacuation and suitably staffed and equipped can perform MEDEVAC.
Prepared assets and opportunity transport
In the US Army, Dedicated CASEVAC describes vehicles and crews reserved exclusively, equipped and trained for this movement task. Designated CASEVAC uses assets that perform other duties and are also tasked with casualty movement for a particular phase or as a contingency. A Platform of Opportunity is a transport asset available at the time that need not be specifically configured or crewed for CASEVAC. A vehicle reserved for CASEVAC still remains a nonmedical platform.
A prepared asset may already have suitable litter positions, securing arrangements and a crew trained for its role. Opportunity transport may enable rapid movement away from immediate danger, but it brings additional problems: the injured person must be loaded and held in position during travel; an attendant needs access to them. A vehicle still delivering supplies may also be committed to a different task.
Untrained handling during carrying, loading or unloading can cause further injury. Unsuitable securing arrangements can allow the person to move during braking, turns or a rough journey. Limited space can make even observation of their condition difficult and prevent necessary care.
From the person’s location to the vehicle
For isolated personnel, the movement question starts with actual mobility. Can the person walk, do they need assistance, or must they be carried? This information affects how forces reach them, how many personnel and what equipment are needed to take them to the pickup point, and how the vehicle must be configured. Several ambulatory people require a different pickup arrangement from several litter patients. Someone who can manage a few steps with assistance has not thereby demonstrated the ability to walk the entire route.
Movement by litter bearers can bridge the gap between the point of injury and the vehicle when roads or another pickup option can only be reached farther away. It places physical demands on the bearers; longer or difficult routes may require relief personnel. A small isolated group may lack these additional people.
Before movement, the group can assess its actual means: who can still carry or assist, what transport equipment is available, what obstacles can be identified along the proposed route, and where movement would expose those involved to an observed threat? Assuming that an accompanying person’s strength or the casualty’s mobility will last to the destination can leave the movement stalled partway along the route. Moving towards another pickup point merely in the expectation that transport will appear there adds an unconfirmed destination to this burden.
Information from the person and group
When contact has actually been established, concrete information helps adapt the movement: the number of people, current location and how it was determined, walking or carrying requirements, observable injuries or symptoms, and changes in condition. Available companions and transport means, identifiable access obstacles and observed enemy activity also matter. A statement such as “two people, one cannot walk, no litter available” describes a different requirement from “two ambulatory people”. In the first case, movement of the casualty who cannot walk and a suitable place in the vehicle must also be arranged.
Known facts and assumptions must be kept separate. The person affected or someone accompanying a casualty can describe what happened, symptoms and measures already taken. Unmeasured values or an assumed medical condition do not belong in a report as established findings. Without established contact, these observations remain useful for the group’s own assessment and a later handover. If mobility or condition changes, the next report or handover needs to include that change.
The location and planned pickup point are also sensitive information. A technically capable enemy may intercept unprotected transmissions and use them against the person or the pickup force. Available, prepared reporting and authentication procedures therefore also need to govern how this information is passed. A precise position does not replace authentication: before taking charge of the person, forces must be able to establish that they are in contact with the intended individual.
Route, destination and handover
CASEVAC may go directly to a treatment facility or first to a location where medical forces take over the onward journey. A casualty collection point alone is not a treatment facility and may be unstaffed. Prepared movement chains therefore have to connect the pickup location, a usable route, the personnel responsible for taking over and available onward transport. If transfer points or facilities move, those involved need the updated information. An outdated destination costs additional movement and may take the person to an area without care.
A suitable destination also depends on medical need and the capabilities actually available at the facility. The shortest route to any building with a medical function may result in another movement if it lacks the required care. During handover, known information must continue with the person: what happened, what injuries or symptoms were observed, how their condition has changed, and what measures have already been taken.
