What Bristow are using is top-end ITAR-controlled commercially available at time of purchase.

You're doing it again. Quoting what you've seen in a press release, a website or a glossy brochure and re-broadcasting it as gospel. Have you actually seen these 'top-end' NVG? Sumpor Stylee seems pretty close to the action and he/she appears to be suggesting that what they're planning on using are anything but 'top end'.
