You know, after this comment I will no longer reply because honestly, I am actually getting a bit annoyed at the idea that people are really complaining over this.

They were already short on troops and bogged down as is, and no other soldiers were manning the turret because there wasn't a need to at the time, as no Husks were near it. Shepard just happened to be walking by at the time.

And really, how would some random soldier manning a turret make the scene better? For starters, you would miss a fun fight. And Shepard manning it makes the situation feel more desperate.
