Once again, a HO takes two pilots two happen. If you do not want to enter into a HO, than DIVE!!!!!!!!!!!!!!!!, or turn. Climbing is a bad idea.
Keeping your guns pointed at the enemy is a sound ACM practice, if the enemy is coming towards you, fire a bust and break off. and manuever to get on his six.
We do not need any special HO rules, icons, messages, etc.
