I'm going to be playing only 6 dudes in this, who are all in the same squad. And since it's a covert op, I won't playing a fleet, just a single squad. So my sheet will be vastly different to that of everyone else. Is that ok?

Err.... No. You still gotta fill out the sheet in its entirety, just maybe not to the extent that some people willingly took it. This is still an NRP so there is still a much greater scale for you to take into account. 

PM the GM if you really really want to just have that single squad told in a linear story. He/she still has the final say on it and if you spin your idea in more detail with maybe a bit more context it might be a legitimately good idea.
