Looks great, Cart - I'll add him to the list of confirmed characters! 
Feel free to jump right into the IC. 

I'm pretty much figuring at the moment, that after months (years?) of fighting retreating battles against the Invid and Haydonites, the Sentinels unit structures are probably a big of a hodge-podge, and tend to have been scraped together from whoever's left to pilot what mecha they have, and do it reliably and effectively. So, I'm going to take a liberty (because REASONS), and say our XT characters are flying together, much as the human characters are as well.
