Okay, well I'm neither a character reviewer nor a Nep expert, but I'll give it a shot.
Some quick, easy stuff.
Go in, and pull up the standard Nep inventory coding. Yours is all over, and includes a lot of things I'm pretty sure we don't have in the setting, like Marine Corp insignia.
History seems a bit... shallow... to me. I don't know, it just seems light.
Strategy isn't a skill. It would be something listed under Survival and military or Fighting normally I believe, possibly leadership. That needs to have a mod decide what to do with it though.
On your other skills, it seems like you didn't include anything but the boilerplate stuff. Personalize them, make them YOUR character's skills. Also, he has no skills that have to do with anything but fighting and war? He can't pull tricks with a knife, or do anything else? It seems like you're trying to make a tank rather than a character meant for interaction. He has no skills that would be of any use for talking to women, or hanging out with his buddies in a bar. Believe me, you can pick up combat skills as you go along.
Personality is almost non-existent. Again, who is he? How would he react if a pretty girl walked up and started hitting on him, if a guy tripped in front of him and landed in a puddle? Make us KNOW who the character is, how he would react. We want a character that's fleshed out and believable.
In his description 'average ID-SOL build'. Elaborate. He's not going to be a complete average, he'll have differences. Are his muscles well defined, or is he just muscular? Tall and thin, or short and solid? Again, make us picture him when we read your description. A good basis to go on is to write it in such a way that an artist could draw him from nothing but your written description.
Overall, it seems like a decent submission. Since I'm nobody official, you don't have to listen to anything I say, but I think it's a good start.
One last thing. If I've made any mistakes, I am extremely sorry. Like I said, I have no Nep characters, and haven't read up much on them.
