Within the close-knit world of former SAS men, it may signify ostracism. A Carlton television series, SAS - The Soldiers' Story begins this week, but with new MoD guidelines in place and increasing bitterness among serving and recently retired SAS men against the handful of retired soldiers who made capital of their experiences, it is likely to be the last.
General Sir Peter de la Billiere, who served with the SAS and was Britain's senior military figure in Saudi Arabia during the Gulf war, said he would not seek re-election as the SAS association's chairman. He is widely seen as the instigator of the rash of SAS books and films.
Senior defence sources told the Independent last week that they did not believe Sir Peter knew the effect that publication of the details of SAS operations during the Gulf, in his book, Storm Command, would have. But having described the exploits of patrol Bravo Two-Zero, deployed in the western Iraqi desert to destroy Scud missiles, it was perhaps inevitable that surviving members of that patrol - one using the pseudonym Andy McNab, the other Chris Ryan - would publish their own accounts, with spectacular success. Whereas McNab and Ryan undoubtedly witnessed the events they described, others may also have jumped on the bandwagon. And whereas the role of the SAS in the Gulf war was relatively straightforward, the SAS may also have been involved in other operations - against drug barons in South America and possibly in the former Soviet Union and Afghanistan - which the Government would not want publicised.
Although many of the procedures described in the books and television series may differ from those currently in use by SAS men in Bosnia - whose language skills and expertise in working with local factions are their prime value - senior officers said they were still concerned.
There are fears within the Hereford-based regiment itself and at the highest defence planning levels, that the mystique of the SAS has been damaged. Its mystique is as important a part of its hitting power as its professional competence.
However, the Carlton series, which re-examines well-trodden ground about the Iranian embassy siege, the war against the IRA, the Falklands and the Gulf, is seen as less damaging than the dramatisation of Chris Ryan's book, The One that Got Away. The latter portrayed the SAS as badly prepared and incompetent.
The spate of "revelations" led to the MoD breaking its traditional "no comment" rule on special forces in the latest Defence White Paper, published on 1 May.
For the first time it featured a few paragraphs on the role of special forces.
"The interests of national security will always come first", it says. "And where necessary the Department [MoD] will pursue all appropriate legal options to prevent the publication of information about the Special Forces which it considers to be potentially damaging."
In the light of such statements, in future it is likely that the provisions of the Official Secrets Act, which apply even after someone has left government services, will be more strictly enforced.
