SERE Level C is advanced military training for personnel at high risk of isolation or exploitation. It combines academic preparation with extensive practical training in survival, evading capture and resisting adversary exploitation. It also prepares the individual for recovery: isolated personnel must sustain themselves, assess their situation and be able to contribute to contact, identification and pickup.
Why risk determines the training level
Isolation risk is the danger of becoming separated from the protection and support of friendly forces. An aircraft over hostile territory can leave its crew isolated after being shot down or suffering a failure; special operations forces may operate far from immediately accessible support because of their mission. The operating area, the way a unit operates and the particular mission determine how likely isolation is. Rank alone does not explain that exposure.
Exploitation risk concerns the harm an adversary can cause by exploiting a captured person. Knowledge of a mission, forces or capabilities may be valuable to the captor; the person's responsibilities and role can give the consequences of captivity particular weight. Questioning can obtain information, and an oral or written statement can be used against friendly forces. Intensive resistance preparation may therefore be necessary where the consequences of capture are especially serious. The US system provides C for personnel at high risk of isolation or facing a significantly increased threat of exploitation if captured.
What C adds to B
In the NATO training model, B includes basic practical survival and evasion training, with resistance taught in the classroom. C extends practical training across all three areas, including resistance in a strictly controlled, realistic training environment.
One US course model combines academic instruction and practical skills with a sustained survival/evasion field exercise, a resistance training laboratory and individual and group debriefing. During the field phase, participants must reconcile sustainment, concealment and movement. In the resistance laboratory, instructors act as the detaining power; participants practise individual conduct and cooperation within a prisoner group. French practical C training uses operational equipment and an opposing force.
The individual's decisions in the field
Once isolation occurs, physical condition, remaining resources and location underpin the next actions. The person must recognise which injury or environmental exposure threatens their ability to move, what protection and sustainment equipment remains available and which objective they can reach. A previously prepared Evasion Plan of Action, or EPA, records intended evasion movements and recovery intentions. It helps friendly forces anticipate the person's possible actions. A route that has since been blocked or an objective that has become inaccessible nevertheless requires a fresh assessment.
Movement must account for detection risk. A moving human shape, a silhouette on a skyline, rattling equipment and traces left behind can reveal the person. They therefore observe from concealed positions, use existing concealment and check visible activity before crossing exposed ground. A rest site needs protection from the environment, concealed access, observable approaches and a way to move on. Someone who withdraws into a location without an exit can be trapped by the first enemy approach.
Sustainment and movement compete for time and strength. Obtaining water, looking for food or improving a protective site may require a longer stay; an enemy search may simultaneously make movement more urgent. Conversely, an exhausted participant may no longer be able to cover the planned distance effectively. One US C training model combines such decisions with search pressure, limited food and restricted sleep. The individual's task is to allocate sustainment, rest and movement so that further travel, observation and, where possible, pickup remain feasible.
What practical resistance prepares for
Capture changes the available actions: the adversary controls movement and contact, while information protection and cohesion become more significant. Resistance includes conduct during questioning and other exploitation attempts, protecting fellow prisoners and maintaining a functioning prisoner group. Disclosed information may endanger other people; special treatment by a captor may undermine group cooperation. Practical training brings these conflicts together in controlled captivity scenarios.
For US military personnel, the Code of Conduct provides a specific framework. When questioned as a prisoner of war, it identifies name, rank, service number and date of birth; the individual is to evade further questions to the utmost of their ability. It also addresses harmful oral or written statements, assistance with escape, refusal of special favours and responsibilities towards fellow prisoners. The senior prisoner takes command and others support lawful orders. French C training also covers detention by non-state actors and the psychological and legal aspects of captivity.
How the individual supports a possible recovery
For the individual, recovery preparation starts with intended movements, personal identification information and the planned contact procedures. An ISOPREP supplies information for identification and authentication; the EPA describes intended actions during isolation. Once contact is actually established, relevant information includes enemy activity, terrain obstacles, the number and condition of people and available signalling devices, as well as location. Communication requires functioning personal equipment and a reachable receiving station. Actual pickup additionally requires suitable available forces, a reachable pickup location and a threat situation that those forces can accept.
Signalling reveals the location and may also expose it to the adversary. Available signals are used according to the prepared or transmitted procedure; authentication information is protected from disclosure. Even precise coordinates do not yet confirm to the recovery force who is at that location. When pickup is imminent, the individual remains concealed until the designated moment, secures equipment and weapons, avoids sudden movements and approaches only when instructed. With aircraft, rotors, propellers and loose items create additional immediate hazards. These actions assist the transfer into the control of a friendly organisation.
National forms of C, Charlie and RtoI
In Germany, C is primarily intended for special operations forces and pilots. It covers advanced survival and evasion skills and appropriate conduct in prisoner-of-war captivity. Resistance to Interrogation, or RtoI, is an additional module, particularly for special operations forces and aircrew. Where it is incorporated into the course, a captivity and questioning phase follows the evasion phase. RtoI therefore develops a particular part of the preparation; it does not name the entire SERE C course.
France uses Charlie as the name of the highest SERE level for aircrew. C preparation combines survival and capture avoidance with practical resistance and procedures to support recovery. It includes personal equipment for movement, position signalling and secure communication. The actual availability of that equipment determines which prepared options the isolated person can use.
In the United Kingdom, C is delivered by the Defence SERE Training Organisation, while B is delivered at unit level. Selection for C follows operational risk and the categorisation of personnel at risk. In the United States, the final E in SERE stands for Escape; the Code of Conduct shapes military resistance training.
