Maybe some scifi nations, as I have some of them figured out for my sci fi setting. If I do something here I don't want to get into minor specifics, being more like brief descriptions and common sense such as general descriptions of range and damage and the rest can be inferred until it becomes important later on and we want to get extra detail for the fun of it. For example, I could say, "they have high powered sniper rifles with medium range for snipers" and we can leave it at that. I glanced over some sheets and it appears like we don't need insane details so that should be fine.

My sci-fi setting is more like star wars and rule of cool stuff rather than engaging the enemy millions of miles away in completely realistic craft. No, I like it where we still need to get up close and personal. Anti-aircraft weaponry can stop aerial bombardments well enough so it doesn't just turn to who has air/space superiority. I like me some land battles.

As for how to write profiles? Hit up any of the currently running space sci-fi NRPs and you'd see. Yeah, they aren't that demanding. Especially if you only want them for this game. As for ranges in sci-fi they tend to be very flexible. Besides with FTL sensors and the distance involved sniping is one of the least likely things to happen in a space battle.
You may want to familiarize yourself with at least a few concepts before trying space battles, though. Let's focus in ground battles or at least one fought on planets since they are less difficult.
