What operation was thwarted by a brigade of about 40 members?
Operation Conservation
Provisional IRA South Armagh Brigade
The South Armagh Brigade of the Provisional Irish Republican Army (IRA) operated during the Troubles in south County Armagh.
 It was organised into two battalions, one around Jonesborough and another around Crossmaglen.
 By the 1990s, the South Armagh Brigade was thought to consist of about 40 members, roughly half of them living south of the border.
 It has allegedly been commanded since the 1970s by Thomas 'Slab' Murphy who is also alleged to be a member of the IRA's Army Council.
 Compared to other brigades, the South Armagh IRA was seen as an 'independent republic' within the republican movement, retaining a battalion organizational structure and not adopting the cell structure the rest of the IRA was forced to adopt after repeated intelligence failures.
Operation Conservation
Operation Conservation was a British Army attempt to ambush a large Provisional Irish Republican Army (IRA) unit along the Dorsey Enclosure, between Cullyhanna and Silverbridge, in south County Armagh.
 The action took place on 6 May 1990.
 The operation was uncovered and thwarted by the IRA South Armagh Brigade.
Nesting (voting districts)
"Nesting" is the delimitation of voting districts for one elected body in order to define the voting districts for another body.
 For example, in California, the State Assembly (the lower house) is composed of 80 members, each one representing 1/80th of California's population, and the State Senate (the upper house) is composed of 40 members, each one representing 1/40th of California's population.
 In this case, the process of nesting could either be first defining the 80 Assembly districts, and then defining the Senate districts as a merge of two Assembly districts, or first defining the 40 Senate districts, and then creating the Assembly districts by splitting each Senate district into two.
 If the Assembly districts and the Senate districts are created independently of each other, then the process of nesting is not used. 10th Mountain Assault Brigade (Ukraine)

The National Assembly is bicameral with the lower house, the Chamber of Deputies, having 40 members elected in single-seat constituencies for a four-year term.
 The upper house, the Shura Council, has 40 members appointed by the King of Bahrain, with the stated aim of giving a voice to minority communities and technocratic experts within the legislative process.
 Supporters of the system refer to long established democracies the United Kingdom and Canada operating with this bicameralism with an appointed upper chamber and an elected lower chamber.
 Opponents of this system point out that unlike the bicameral systems in the UK and Canada, the Bahraini system gives the unelected upper house equal or more legislative power than the elected lower house, allowing the King to control all legislation.
 Opponents also point out that the current system was imposed unilaterally by the King, violating the and a 2001 signed agreement with the Bahraini opposition. Alaska Legislature
