The character himself looks solid enough. Good detail in his descriptions and personality. My fellow Nepleslian GM Sigma and Aendri are correct in their concerns for Cormac's history, however. Sigma may seem a bit heavy-handed, but his concerns are valid. I too am a apprehensive to passing this, for a few easily fixable reasons.

Firstly, I myself am a bit concerned with the fact that this Civil War seemed to take precedence over Cormac's history; it reads like you are describing the civil war first and Cormac's participation second. I am not a character mod, and I actually have little jurisdiction over this character as Cormac is actually labeled as independent.
If you are to rewrite this history setting, I strongly suggest trimming it down to details that pertain directly to Cormac. I admire that you wish to describe the Civil War properly, but it seems to take precedence over Cormac, in his own biographical page.
Secondly, the Civil War itself. Nepleslia isn't one to shirk against a struggle. In fact, a Civil War is quite proper for the nation. However, my concern is that something of this caliber would have been dealt with by our military once it escalated to the point of the local government 'losing control' of the situation. And given how tense things are with the NMX currently, the Star Military would have dealt a very swift and very firm hand in silencing this civil disorder; sort of a "we don't have time for this nonsense" heavy-handed reaction.
The only reason our last Civil War with the Nepleslian Reds was considered an ordeal was because the entire planet of Kennewes was essentially against the reigning government party. And even they didn't last all that long.
My advice here would be consider rewriting this Civil War and bringing it down a few levels into something of a "very bad street war". Anything below the point where the local Kovax Government would consider things "out of their control" would work fine, because at the very least, it will safely keep our military from making an example of the rebellion. The gas bombs are actually fine; I imagine our colonial Nepleslian communities deal with that jibberjabber every day, or worse. This civil unrest can still butt heads with the local government, but not enough to the point where Kovax officials would request help from Nepleslia's military to regain control.
You don't have to strike it completely. Simply alteration of the scale should suffice.

On the tone of issues of lesser importance, your skills section could use some work.
My personal usage of the skills section involves naming the skill (obtained from the
list of skills) and simply explaining how the character uses said skill. Throw some of his personality in the description of Cormac using the skill and it will really pop out and help us identify with the guy a lot more. As an example, the first skill exerted from my linked article.
Fighting and Physical
Unfeeling Killer
Sho excels in physical warfare; it's about the only thing that he does exceptionally well. When in combat Sho is calm, collected and brutally efficient, preferring results over flourish. The man has a quick, analytical mind when it comes to fighting, and his personal ability to generally remove all emotion from fighting and the act of killing aids him with the slight edge needed to excel in such areas, removing hesitation and other associated feelings. It is because of his ability to disassociate his emotions from the act of harming that Sho pushes himself to excel at combat and related ventures. Sho does not particularly enjoy the act of killing or combat in general; he simply feels that it is perhaps one of the only things he can do well, and carries a strange, unexplainable pride in his abilities.
Sho Katsumoto is well versed in many common weapons found in several nations, ranging from pistols to powered armor. Sho has an affection for the latest innovations and more technologically advanced weapons, however, preferring the new models of not only weapons, but anything and everything, over the old versions. This preference is based to his fixation of “efficiency”; newer, more up to date equipment often means the removal of flaws and the addition of more beneficial attributes. Although he is perfectly capable of wielding a weapon of older design, Sho dislikes doing so.
It's not a requirement to do it this way, by any means, but in the form of me giving you advice, it would be this; a little description goes a long way in conveying your character.
Overall, though, I get a good feeling from the character. You put some good detail in his description and personality, and you made a very good effort with the history. Although it may not appear we appreciated it, I personally liked the thought you put into it. It says good things about you as a player.
If you have any further questions about Nepleslia as a setting, feel free to ask me. It's my job, after all.
