Resistance to interrogation
R2I, RTI, or resistance to interrogation is a name for a set of techniques taught to UK troops, and other NATO soldiers with the express purpose of preparing them, after capture by the enemy, to resist interrogation techniques such as humiliation and torture.
The trainees undergo practices such as hooding, sleep deprivation, time disorientation, prolonged nakedness, sexual humiliation and deprivation of warmth, water and food. Many of these techniques are against international law if used in interrogations.
Standard RTI for most special military branches of American and European governments covers both tortures that are condemned by the United Nations and interrogation techniques that are considered legitimate, usually presented along a sliding scale. For instance, a soldier would be subjected to slight discomforts before being subjected to more torturous techniques.
RTI is a product of the market for military information, which has been in place since as early as when Sun Tzu wrote The Art of War. Especially moving into modern times, when information and technology is often more important than numbers in combat, and when torture has been used less often to humiliate and more often to extract information, RTI has become an integral part of military training in most Western countries in one way or another.
