NVG etc
There is no "They" yet, when there is "they" will probably consist of quite a few ex-mil sarboys/SH etc who will have the requisite experience. Besides we all started with zero NVG experience and managed not to kill ourselves. If a commercial company needs a particular skill-set they will simply buy it in. The companies in the running for SARH have quite a few ex-mil personnel on their books and they are very aware of all of the problems and concerns.
