Korris Skip 

This is a quick example of how to skip the first AA gun on the Admiral Korris mission for ME3.
In case it's not apparent you run by the AA gun without killing any enemies then. The game then automatically puts you at the gun to disable it. Then again you just keep running to the next area abandoning your squad mate.
This clip has no audio as I had some sync issues when trying to get the clip and I don't have time to fix it.
