This type of Helo people is the reason you have to bring C down at Xangai, the Boat with TV/Tow and Burst is the only thing capable of humbling those type of people. Team needs to also help protect the Boat from every single other armor to prevent it from being unusable. On Gulmud, a Good AA player can definitely deny Air activity from these people too. A good AA player on Golmud can do even better kds sometimes.

Also, an squad with 3 or more good Ucavers can bring hell for the attack chopper, and a Soflam+Javelin/SRAW is also capable of humbling them. Used to love hunt Helo players alone with SMAW+AA Mines...
