I love how Maya's using the quartermaster as her mobile Ops and Intel specialist, keeping her apprised of the full scope of the mission. That's an inspired use of the man's experience and specialization.
However, Maya's seriously deluding herself as to the lives this mission will cost Starfleet... and the quartermaster knows this.
Redmond likely won't survive the assault, and they all know it. And he will only be one of many to fall for the cause.
