I use 3.5e as written, and the scenario of a mass fight that involves NPC classes occurs once in a while.
I've found the Commoner rules work quite well for things like people in a crowd being attacked by monsters (in "The Speaker in Dreams" WOTC module) and a village militia being attacked by orcs and werewolf-orcs (in a scenario I created).
Commoners CAN hit basic monsters like orcs and dire rats, even with just a dagger (for the city dwellers in a crowd) or a spear (village militia).
The difference compared to Experts or Warriors is mostly in their level of equipment -- a Commoner 1 Village Militiaman with two spears, no armor, no shield is considerably less effective than a Warrior 1 City Guard with a longsword, light crossbow, and studded leather armor or at best chainmail.
The difference to a PC Fighter 1 is more pronounced -- better stats, feats, possibly better equipment, and the big one -- Max hit points.
So yes, most of what a Fighter can do, an Expert or Commoner or Aristocrat can also do, but the Fighter is much more successful at.
That works just right for me.
Oh, and rarely, I've had an NPC "manifest" a PC class in midfight. I did that once (in AD&D rules) when a kid who was raised by an LG cleric was fighting invaders of the Keep on the Borderlands and did much better than expected. Faith plus orphan raised by LG cleric plus the clear will of the gawds (as expressed through the dice) = instant paladin!
And I've referred to that sort of thing in the backstory of a villain once, when a PC got to know her pretty well and they were talking about their pasts. She became a cleric of Asmodeus because she prayed to him when Iuz was destroying her village, and she miraculously gained the power to Turn Undead and heal herself.
