From my "armchair" the British Army and RUC (police) used fixed and mobile TCPs in Northern Ireland throughout. There have been a number of open source comments on the gains, in particular the remarks in the history of the Ulster Defence Regiment (UDR), a locally recruited Army unit (A Testimony to Courage, by John Potter, pub. 2001).

On the mainland the police and sometimes with other agencies have mounted TCPs for law enforcement primarily. They've also been used a SOP for CT work, invariably when there is an alert or alas after an attack.

UK use of TCPs has been greatly enhanced by the use of Automatic Number Plate Recognition (ANPR) cameras; which has increased the "hit" rate even if thousands of vehicles pass through. This tactic is based on a document in the public domain: http://www.acpo.police.uk/asp/polici...5_12x04x05.doc

I appreciate in COIN arenas these tactics may look bizarre.

In UK police use TCPs can attract criticism as they are invariably not explained, even to those who are stopped and not prosecuted etc.
