	The coordination necessary to pilot a helicopter is akin to operating a yoyo with your left hand while spinning a pie plate on the tip of your right index finger while you're balancing full glasses of water on top of your feet. Piloting an attack helicopter in combat is like doing all of that while riding a twelve point buck through the woods in the middle of hunting season. Mamba pilots have to be pretty nervy just to get through the training program. "Attack helicopters come in two varieties: Bigger, heavily armored slower ones, and smaller, faster ones with no armor at all. Mambas fall into the latter category. Gyro-Vipers tend to be fast, decisive thinkers with a self-assured confidence in their flying skills... And they don't look back."
