SERE Level A

SERE Level A is the foundational level of preparation for military isolation. It teaches potentially isolated military or civilian personnel how to preserve their ability to act, evade capture, deal with captivity and adversary exploitation, and contribute to their recovery. In the NATO training model, A is assigned to personnel at low risk of isolation or exploitation. The training format and participant groups are determined nationally.

Risk and national training formats

Risk categorisation considers the unit and occupational role, the mission and operating procedures, and the individual's knowledge and responsibilities. Alongside the likelihood of isolation, it considers the consequences of adversary exploitation. The required SERE preparation therefore follows the mission profile. In the NATO framework, Level A includes basic academic instruction as a minimum, delivered through a briefing or online course; basic practical survival training in a controlled environment may be added.

The Bundeswehr describes A as exclusively theoretical training on potential dangers, survival in a hostile environment and the basics of personnel recovery. In France, the theoretical foundational level is also called Alpha. The French foundational profile specifies A for all personnel deployed in the land part of an operational area and combines it with a theatre-specific refresher before deployment. Basic preparation therefore also reaches people whose missions subsequently require a higher SERE level.

The US programme SERE 100.2 delivers Level A content online and uses different modules for military and civilian personnel. The distinction concerns their respective responsibilities and conduct frameworks during isolation and captivity. The military Code of Conduct and the Principles of Behavior intended for civilian defence employees and civilian contractors authorised to accompany the force are separate frameworks. SERE 100.2 names a US training programme; Level A names the training level.

Personal tasks during isolation

Isolation occurs when a person or group becomes separated from their unit or organisation and is no longer under that organisation's direct or procedural control. An ambush, crash or vehicle breakdown can bring injuries, equipment loss and adversary threats at the same time. Personal assessment therefore considers physical condition, the resources actually retained, location and threat. When deciding whether to stay or move, the person also needs to assess whether a known destination is reachable and whether the route permits sustainment and movement.

The French A profile covers protection, location, water and food, physiological and time limitations, personal equipment and military first-aid fundamentals. These subjects explain different tasks: protection from wind and rain reduces exposure to weather, while insulation beneath the body reduces heat loss to the ground. Water must be obtained, made safe to drink and then stored with protection against recontamination. Injuries, water reserves and opportunities to rest help determine the distance and pace the person can manage. Equipment considerations concern the means still accessible after separation, such as retained protection, navigation and signalling aids.

Evasion here means avoiding capture. A short route may cross open ground; a concealed detour costs additional time and effort. Movement attracts attention, shiny objects reflect light and noise can reveal a person's presence. Terrain and vegetation screen the person only from particular observation directions. A resting place therefore needs to conceal body outline and movement, allow observation of its approaches and retain a way out if a threat comes closer. Level A addresses these relationships as a foundation for personal decisions; extended practical evasion phases belong to further training.

Captivity and information protection

Captivity is addressed at A because a detained person may provide information, be used for propaganda or become leverage against their own side. The French profile distinguishes prisoner-of-war captivity, government or non-government detention, and hostage-taking. Prisoner-of-war captivity belongs to the legal framework of an international armed conflict; certain authorised civilians accompanying armed forces can fall within it alongside members of those forces. Hostage-taking uses threats to life, safety or release to compel a third party to act. Military and civilian status therefore do not create a simple division into prisoners of war and hostages.

Foundational understanding includes protecting information, surviving captivity and the individual's national conduct framework. Details about the mission, forces or other captives can benefit an adversary. For US military personnel who become prisoners of war, the Code of Conduct requires loyalty to fellow prisoners and prohibits information or actions that could harm them. When questioned, it specifies name, rank, service number and date of birth as the information to be given; the individual is to evade further questions to the utmost of their ability. It also prohibits oral or written statements harmful to their country and its allies.

These military duties explain part of SERE 100.2's military focus. Civilian defence employees and civilian contractors authorised to accompany the force prepare under the Principles of Behavior provided for their status. Instruction designed solely around the military Code of Conduct does not cover that civilian conduct framework. At the foundational level, the subjects are the significance of status, information and adversary exploitation; practical captivity and resistance scenarios do not thereby become part of A.

Contributing to recovery

Personnel recovery includes preparation, the recovery of isolated personnel and their subsequent reintegration. The isolated person contributes through prepared conduct, position information, signals and cooperation when contact actually occurs. In NATO preparation, national and mission-specific guidance may require an Evasion Plan of Action, or EPA, and an Isolated Personnel Report, or ISOPREP. Before the mission, the EPA records intended conduct and evasion movements so that recovery forces can better anticipate possible locations and movements. The ISOPREP contains information held in advance for identification and authentication. The applicable guidance determines who needs these documents; their functions differ from a current position report.

A position report states the current location; an available communications link can also carry information about injuries, group size and threats. A visible signal makes that location detectable to an observer. This requires recognisable contrast against the surroundings and a line of sight to the receiver. Infrared signals require compatible observation equipment at the receiving end. Agreed contact times, signals and no-radio procedures help direct the use of personal equipment. A conspicuous light or panel can also attract adversary observers; in a threatened environment, the person therefore directs their signalling towards the planned contact or confirmed friendly forces.

Authentication checks whether the contact is in fact the expected person. Even precise coordinates do not remove the risk of deception or adversary control of a contact: recovery forces may be especially vulnerable during pickup. The individual therefore protects the prepared authentication information and uses the specified procedure. In the French A profile, the emphasis is on simple position signals and conduct towards recovery forces; a generic identification or authentication method belongs to final pre-deployment preparation when theatre guidance provides for it.

During an actual ground or landing recovery, the person helps the force locate them, adopts a non-threatening posture, secures weapons and loose equipment, and avoids sudden movement. They approach the vehicle only when instructed. Through an available link, they report particularly the number of people, injuries and adversary activity at the recovery site. Whether forces can reach and recover them depends on factors including location, condition, authentication, available capabilities and threats to both sides.

Position among A, B and C

In the NATO model, the levels differ in their assigned risk and the extent of practical training. The Bundeswehr also describes an evasion exercise and conduct during recovery at B; C develops survival and evasion further, together with appropriate behaviour as a prisoner of war.
