This is the title of a piece on Kings of War and is written by a recently retired senior UK police officer:http://kingsofwar.org.uk/2015/11/ccl...-the-militia/?

The introduction by an Editor starts with:
Today in CCLKOW we are reorienting you to the homeland and the problems of interoperability between police and the armed forces. Even without the Paris Attacks earlier this month, the subject of mastering the ‘JIIM’ environment is critical, both in military operations at home and abroad. To discuss this, I am very happy to bring to you a special guest writer, Ian Wiggett, recently retired as an Assistant Chief Constable from Greater Manchester Police. It should be understood, then, that this piece is written from the British perspective, which includes a significant difference with respect to the use of force by the police, particularly as concerns the generally disarmed stance. Nevertheless, the issue of integrating a military response to an attack to the homeland matters even to the US.
