The Rank and file:
Gnoll hordes use a variety of bows and axes, although they often seem to end up with weapons such as picks and warhammers after slaying dwarven patrols. Now that the PC's have slain the gnoll's primary weapon supplier, there will probably be a slow tend towards clubs and spears as the supply of steel weapons dribbles away. The gnolls rely primarily on animal hide for armor.
Sabrekin (large Sabre-tooth people with psionic abilities) use spears, and upgraded-for-size punching daggers that are shaped like cats claws. Most have some level of psionic ability, so armor isn't as predominant as Inertial Armor. No-one knows much about the Sabrekin, and although they appear savage the slow realisation that they possess metalworking (or crystal working, which is probably more accurate) skills will sink in.
Gauntian Warriors tend to use a variety of weapons, although there is a preference for those weapons which cause the most pain. Scimitars, Tridents, Flails, Scythes and Dire Flails. Shields aren't popular, and armor is typically no heavier than a Breastplate for the rank and file. Spikes are popular, and the Spiked Gauntlet is a fairly popular backup weapon. Gauntians, for some reason, have never grasped the concept of an army as unified and tend to focus on inspiring terror rather than organised fighting.
I also once had a group of druid-led hobgoblins that focused on Ranger skills, worshipping a demonic snake. Lots of snake-skin leather armor, quarterstaves tipped with snake fangs (which did actually add magic effects sometimes) and precise shot with the shortbow.
Upper Management:
Not all of these have been encountered yet, but they're waiting in the wings:
A Half-orc ranger in studded leather, using a orcish double axe. It's frightening the amount of damage those things can do in one round, and I'm thinking I'll include another one on a heavily armored fighter at some point.
A Fighter specialised in shiruken (or, in his case, throwing knives) whose schtick is getting a horde of blades off in one round. Usually poisoned. Light armor, lots of mobility.
A Monk heading towards a modified Lasher prestige class. His whip dagger is actally a braided length of his own hair, with a long metal spike woven into the tip. Usually poisoned.
A demon-possesed dwarf wearing heavy armor and running around with the Ugrosh. He's slow, but he'll be a terror when carving his way throuth rank and file enemies for the big-bad he serves while the master keeps the PC's occupied.
At one point, a Mages army of goblin assasins will probably show up wearing jet black ninja garb, armed with paired sickles and bola's.
A human warrior with a Longspear, who was originally providing weapons to the gnolls. It's interesting to see how someone with mobility and a longspear can keep themselves repossitioned, and a true level of cruelty would be to create two fighter rogues who flank opponents with reach to gain the sneak attack.
