As Milkman pointed out the turret part feels out of place and takes away from the emotional goodbyes directly before.

If they had marines on the turret defending it would have added to the atmosphere; make you feel like you are running out of time with the Reapers knocking on your front door. Without shoving this feel down your throat. Of course this is assuming you need to keep that turret there at all.
