David,
Thanks for the response. I realize that building an organization like the Ulster Defense Regiment, and the Home Service Force of the Royal Irish Reg, was a stop gap during the worst part of the war ("troubles") that turned into the "least bad" solution long term.

It is easy to forget that the British Army executed Operation Motorman in 1972 for 6 months with a 28k+ pax Division- not counting the UDR or the Royal Ulster Constab. Add it all up and the Government forces were probably putting close 40k (or more?) armed personnel on the streets (police, Regular Army, UDR, HSF etc).

As an "Full Time" Army National Guardsman - I am always interested in how other "reservist" or "Home Service Force" units organize and operate.
