I'll write it up as best I can remember; I may be able to post some relevant excerpts from Dragon Magazine later on.
Roger Moore wrote an editorial in dragon back in the 1980's about the "they're only kobolds" phrase. He had a DM back in the military, whom he referred to as Tucker. Tucker's kobolds were nasty kobolds that lived in the first level of a multi-level dungeon.
The first time their 10th level 1st edition party encountered them, they were shot at from murder holes in the ceiling, as boiling oil, flaming debris, etc. were dropped on them. When the kobolds did appear in person, it was usually equipped in cut-down plate mail, hiding behind flaming piles of debris pushed with large poles, shooting steel-tipped crossbow bolts and javelins at the party. The party could not retaliate with cloudkills and fireballs, since the area of effect in the small passageways would fry them too, at the expense of 4 or 5 kobolds. The kobolds stole the equipment they left behind (to run faster), they would eat the party's pack mules, and generally survive no matter what. It was like getting hit with an Fire Ant Colony, only the ants were packing heat.
Future forays into the dungeon meant RUNNING past the kobolds as quickly as possible, hoping to take minimal damage as they headed for the 2nd level, or for the exits when returning.
In all, Tucker's Kobolds was such an entertaining tale that they were the origins of the Kobolds of Dragon Mountain, and live on in Gary Gygax's "Old Guard" Kobolds of Castle Greyhawk, tromping in military fashion, using tactics to take down foes much mroe powerful than they.
In 3E, Tucker's Kobolds would still work, but they would ALL be likely 3rd level rogues with potions of invisibility, with a 12th level sorcerer backing them up making potions and magical traps to lure fresh bait, er, adventurers, into.
