I've run a search for this problem and found no answer so maybe someone here can help me.
On the attack chopper training mission, i fly to the hill near the target range and commence my pop ups.
I hear a voice say, for example, "attack Shilka" and a corresponding white box appears around the target. But the gunner hardly ever locks onto the tank, Shilka or APC. it has managed on occasion but it seems to random and not related to any of my key presses. The "lock" command seems to be, by default, the TAB key or the RMB, but neither seems to make a difference.
Please can someone throw some light on what, if anything, i'm doing wrong.
