In military SERE, escape means getting free after having been captured by an adversary. Its purpose is to leave the captor’s control and make a return to friendly control possible again. The escapee may remain isolated, with few remaining resources, an enemy threat and no reliably reachable support.
Escape from captivity
In captivity, the captor determines where the person may stay and which movements or resources remain accessible. Preparation therefore concerns both a usable opportunity and the situation after getting free: what movement the person’s condition allows, which resources actually remain and how recapture can be avoided. A map, radio or supplies carried before capture must not be treated as still available.
Resistance protects the person and fellow captives against enemy exploitation, including the disclosure of military information or harmful statements about comrades. After getting free, the person may need to evade again to avoid recapture and continue moving with the resources that remain. In military English, an escapee is a person who has been physically captured by the enemy and has succeeded in getting free.
US conduct framework and fellow prisoners
For members of the US Armed Forces, the Code of Conduct connects resistance to enemy exploitation with efforts to escape and to help other prisoners escape. In communal prisoner-of-war detention, prisoners prepare to exploit escape opportunities under the guidance and supervision of the senior military prisoner. An attempt must also take account of the welfare of prisoners who remain behind.
Leadership, care of the sick and wounded, and protecting fellow prisoners against harmful disclosures remain responsibilities. A person leaving the group changes its remaining capacity to fulfil those responsibilities.
The US conduct framework also prohibits accepting parole agreements or special favours from the enemy. An agreement may offer release or reduced restraint in return for a promise not to bear arms; a privilege may also be offered in exchange for a pledge not to attempt escape. For the prisoner, this directly affects later freedom of movement and action. The Code is a national military conduct framework; offences are separately defined under US military law.
The British duty to take reasonable steps
British service law addresses a person subject to service law who has been captured by an enemy: if the person knows of steps that could be taken to rejoin the armed forces, could reasonably be expected to take them and fails to do so without lawful excuse, that failure is an offence. It is also an offence, without lawful excuse, intentionally to prevent or discourage another captured person subject to service law from taking such reasonable steps.
Escape attempts and prisoner-of-war law
For prisoners of war, international law distinguishes an attempt that has not yet succeeded from a successful escape. Escape is deemed successful when the person joins their own or allied armed forces, leaves territory controlled by the Detaining Power or its ally, or joins a ship flying their own or an allied flag in the Detaining Power’s territorial waters, with the ship outside that Power’s control. A person subsequently recaptured may not be punished for that previous successful escape. Leaving the place of detention can therefore already constitute escape while this legal threshold of success has yet to be reached.
An unsuccessful escape attempt in itself may receive only disciplinary punishment, even if repeated. The same applies to helping an escape or an escape attempt. Acts committed solely to facilitate escape and involving no violence against life or limb likewise fall within this disciplinary limit. Violence against people does not fall within the same limitation. Armed guards remain an immediate danger: weapons may be used against prisoners of war, especially those escaping or attempting to escape, only as an extreme measure and following warnings appropriate to the circumstances.
After getting free
After leaving custody, the person must assess the new situation: injuries and mobility, equipment that actually remains, location and the enemy threat. Concealment provides an opportunity to make this assessment and observe the surroundings. Further movement should use concealed areas where possible; observation and assessment of the next stretch are needed before leaving one. Exhaustion, missing equipment and the risk of recapture determine which movement is feasible.
A communication device that remains available may support recovery if there is a usable connection. A visual signal or another sign helps locate the person if it is recognised by suitable forces capable of actually reaching them. A transmission or signal may also reveal the person’s position to the enemy. Before using it, the prospect of reaching friendly forces must therefore be weighed against the risk of hostile detection. Prepared identity and evasion information may support the necessary checks; an original movement intention does not replace a current location report after captivity. Even when contact exists, the person remains outside friendly custody until physically recovered or until they join their own or friendly forces.
The US expanded form of SERE ends in escape. NATO uses extraction while also including preparation to resist and escape after capture. Extraction emphasises physical reception and recovery.
