Yes, no doubt about it the USA can put the finest things in the worst environments and built it to hold up... the question is who did Vortex get to do it, and how good is it vs the high end "other guys" as this is a flagship product.
Vortex < NASA or DoD, especially if it's consumer market stuff.
I wouldn't be surprised if the military grade vs consumer had differences (of supposedly the same product) be it extra testing or different glass oem.
