He means the visual effects produced by a helicopter when it is close to the ground, it looks similar to sand or dust flying around.

Unless it's changed since I asked Rocket about wildlife, they are currently uncommon to reduce lag.

As I have found it, nights usually consist of the sun going down a few hours before the moon comes out. Unless I'm wrong, this is a core feature of Arma 2 and it is to allow missions to be held in pure darkness for better NVG usage. In DayZ, this might be annoying for some/most people but I don't know if the mod can change the coding of the day/night cycle. On average, the moon comes out at around midnight and is enough to allow limited vision without additional lighting. Many people don't see the moon coming out because they don't stay up late enough. (Understandable for those who work or go to school).

Because as Rocket said, Arma 2 OA/PMC/BAF units are the only ones that can use backpacks.
