Hey mate, i have been reading through that book again, The Operators by James Rennie about 14 Company, and id forgotten how interesting it was. Some things i have noted so far. It says 14 Company was founded in 1974 and that during that time recruits were trained by the SAS (like you said) but that by the 80's the Det had it's own specialist training officers most of whom were also active on the ground at certain times in NI. It also says that by this time a number of SAS/SBS were also going through the selection process so that they could learn the specialist techniques of the Det but they would go back to their units as they would never be a part of the Det in the field. Rennie also mentions that the pay was more than SAS/SBS but does'nt actually say what it was due to the nature of the work. It mentions that the Det had access to equipment that the SAS/SBS could only dream about and there was an individual working for them who basically spent all year going around the world buying up the latest spy gear and new weapons that came up on the market.
The bit i thought would interest you and
@PhilM is towards the end of the book when for about 10 pages he talks about what happened at that IRA funeral you mentioned. Basically he says that the 2 individuals involved were members of the RUC intel unit, and that one of them (who was known for being a bit wayward) decided (unauthorised) to take a newbie soldier round the most dangerous esates showing him 'the ropes' I guess the question from this is that if it was unauthorised then, how did they get their firearms signed out? By the time this incident happened Rennie was an officer and he says he watched it unfold from the control room and that he seriously thought about quiting there and then. It's a great read and has a bit of humour thrown in as it's quite obvious that Rennie fancied one of the female instuctors despite having a girlfriend, and he clearly turns into a little boy everytime he is in her company, you should have a look for it.
