To succeed in their ambition, they will have to survive a gruelling physical examination. They should also have to pass the sternest of character tests, one that establishes their motives for wanting to join the unit.
That is now particularly essential because there was good reason for people having to spend several years in the regular army before they could apply for the SAS. That period teaches discipline and dedication, and weeds out those without the required temperament and ability. Now, those fast-tracked into the SAS will simply have to attend basic army training before rejoining the unit. That hardly seems sufficient.
The army says its new approach will provide a "wider range of people and backgrounds to choose from". This smacks of the flawed thinking that has led also to ambassadorial appointments being opened to men and women from the private sector.
No longer will the art of diplomacy have to be learned through a career in the Ministry of Foreign Affairs. Instead, it can be picked up, apparently, at the drop of a hat. Now, it seems people will be selected for the SAS without having anything much in the way of military knowledge or experience.
The army suggests this approach will strengthen the high levels of achievement of the unit, and "there is no intention that the NZSAS will be lowering its very high entry standards".
That statement does not withstand even a cursory examination. The very fact that people will enter the unit with only a brief experience of the regular army means the entry standard will be lower. At the very least, it will take the SAS far longer to mould them into soldiers capable of upholding its reputation.
It is also worth considering what this process will do for regular army recruitment. And what its impact will be on troops who have slogged away in that force for a lengthy period with the eventual aim of joining the SAS. It cannot be conducive to morale, and it cannot make it any easier to attract people willing to undertake relatively mundane peacekeeping work.
A phenomenon which asserts that Joe Citizen can quite easily walk into a highly specialised job seems to be taking root. If only it were that simple. In the SAS, the potential for serious consequences, both for the unit and the country, is particularly high.
All possible care must be taken to ensure recruits have the right character, background and training. The fast-tracking of recruitment makes that far less likely.
