Police Special Response Teams are special weapons and tactics (SWAT) units trained to intervene in situations such as terrorist attacks, active shooters, high risk arrests etc.
As shown here, they may be called in to deal with scenarios at military installations.
In such cases they may co-ordinate with the installation's military police special reaction team.
