Sorry, if you already know this but STT still flickers between two targets that are directly in front of you...but this only happened in VACQ...also when going to guns, targets are automatically locked by what appears to be GACQ, but there is no HUD moniker displayed to tell you that. WACQ appears to work as you can see and BST has always worked for me. I'm including the track since the topic title has not been changed to include more, dare I say bugs, than just STT obtained by locking up a blip on the radar..at the very end, you can see the lock flickers back and forth between targets....again, sorry if this is all known acquisition_modes.trk
