BRANCH: UNSC Navy
At the end of the day, there are half a dozen CO’s we could easily slot here, but there’s only one who I’d trust with my life and that’s Keyes. Having worked with him several times over the last decade, I can attest to his innate prowess in astrogation and naval warfare, but more importantly, the man is just plain fearless. I would definitely use “reckless” to describe anyone who I’d thought fit the bill, but I’ve found no fault in his tactics. He’s handled some things that even I can’t really quantify or explain, most recently the “Loop” deal at Sigma Octanus IV.
He’d have been the first name on my list if I was the one making it.
