Well, his callsign would place him about Gamma 3, wouldn't it? I mean, for all we know, he probably is.
But he's still a Lieutenant, somewhere near the rank of Cordova or even Christopher Pike (*cough* sorry, Snipes). Look at how confident they speak, in briefings? And can you imagine them screaming like Lt. Ash?
If they were the buggers involved in first contact with the shivans, then... yeah, actually, I could. Let's see, Black and red ships that you (realistically) could barely see, you can't target, when you hit them your weapons do nothing, oh and they just wiped the floor with your wing, and the Vasudan ships you were skirmishing with, with indecent ease.
Yeah, I think they'd be pretty terrified too.
