As a matter of fact the Netherlands has lost 2 Chinooks, an Apache helicopter and an F-16 (pilot was killed) in Afghanistan since jan 2005. All accidents though, at least that is what the MOD has claimed. But a few of the other Apaches were damaged by small arms when they were checked after their missions. So they aren't really that fragile unless they get hit in a critical spot.
And the difference is that NATO is fighting an insurgency while the Russians were fighting a large resistance force that was trained and equipped by Pakistan and the US.
