Close-range tank sentinel of the shotgun variety.
The overlap even has layers, as Elerlia is pretty close in terms of personality (and even age and race by sheer chance) to what I had.

Either way, I'm like 95% through a turian infiltrator, just the psyche analysis section left (personality descriptions, the bane of my characterisation). Crew as it is now seems like it neds someone for long range anyway.
