Escaping through the air might sound simple, but in modern warfare, being formidable doesn't guarantee invincibility; before bullets, everyone is equal.
The Northwest Wind Air Defense Missile, although also touted as a portable missile, is not just a mere missile, but can form a unit of an air defense system.
The land-based Northwest Wind Missile alone has three modes: a two-person set up with a tripod as a portable air defense system, the same Northwest Wind Air Defense Missile mounted on a vehicle equipped with a search radar can detect aerial targets from several kilometers away. It's capable of shooting down not just planes but also cruise missiles. Then there's the ground-based air defense version, which uses a large radar for even longer-range searches, while a smaller radar has a shorter range. However, the notion of helicopters attempting to charge past a missile position before being detected by search radar is impossible.
