Sometimes when you switch soldiers, even if they are right next to your first soldier, the game often swings the camera waaaaaaaaay away before actually getting into the soldier.
This is extremely disorientating! It also glitches further and has you get stuck on the other side of the wall for a moment after gaining control before it then switches you into the actual view the soldier would have.
Very bad for the game if new players encounter this and it gets them killed!
