I haven't read the entire thing. I just skimmed but the word "emergency" is thrown around a lot.

That is an eyeful.

Segregation. I/R populations include numerous types or groups of individuals that must be
segregated for a variety of reasons. I/R populations are segregated based on their legal status
(according to DOD and Army policies) and their gender. Juveniles within the I/R population are
typically segregated from the general population. Detainees may also be segregated by ethnic
and family groups and further segregated to protect vulnerable individuals. Additionally,
detainees may be categorized by behavior (cooperative, neutral, or combative) to accurately
resource guards and facilities. Individuals within the I/R population may also be segregated to
prevent self-harm. Although segregation may not be requested or conducted for the purpose of
facilitating interrogation, interrogators may interrogate detainees who have been properly
segregated. (See DODD 3115.09.)
