Depends on system, though I think that in heroic fantasy there should be a gap between epic heroes/villains and commoners to highlight the heroes'/villains' larger-than-life nature and to make higher levels meaningful.
In most retro-clones, if a typical commoner NPC needs stats (and in many cases they don't), he'd be level 0. Most common guards are level 0, while veterans and tough guards are level 1 and really elite ones are level 3. High level PCs - even level 5 ones with a Fireball once a day - are going to be able to ready kick the a$$ of many ordinary guards - this is intentional and, IMHO, it fits the genre.
In Stars Without Number, non-heroic NPCs don't have levels but are rather statted like monsters and have appropriate skills. Anyhow, rank-and-file guards shouldn't have much more than 1-3 HD. An elite veteran (say, a level 5 Warrior) is going to wipe the floor with conscripts any day, though their weapons would typically still be painful to him or her.
Classic Traveller is far more realistic, and skill levels (there are no class levels in Classic Traveller) advance with job experience, but the typical colonist, guard or conscript is usually going to have 1-3 terms of experience under his or her belt, meaning a few skills of 2 or lower (usually just 1), and maybe a single skill of 3 for professionals.
