some way to activate the engine internal guidance system for script created missiles would be really helpful in some circumstances. (i'm talking about the system you have when you lock a vehicle with the right mouse button with the titan launcher)
something like setMissileTarget would be great.
missile = createVehicle ["M_Titan_AT", getMarkerPos "missile1Marker", , 0, "FLY"];
missile setMissileTarget EnemyTankTarget
