how to set the camera at eye level and looking where the player looks?

player remoteControl _unit;
_unit switchCamera "internal";
objNull remoteControl _unit; // removes the remoteControlling
// whatever happens in between
player switchCamera "internal";  // returns to the player

In a units init box for testing. Ignore the billboard flipping up side down when turning, that is just my horrendous vector maths  . Just wanted to provide a visual example. Maybe someone will chip in and fix it.
