They are Argentine ants. Check out this excerpt from the Wiki page:

Argentine ants are a common household pest, often entering structures in search of food or water (particularly during dry or hot weather), or to escape flooded nests during periods of heavy rainfall. Argentine ant colonies almost invariably have many reproductive queens, as many as eight for every 1,000 workers, so eliminating a single queen does not stop the colony's ability to breed. When they invade a kitchen, it is not uncommon to see two or three queens foraging along with the workers.

Just as I suspected, those "supertankers" WERE the queens; I knew it when I challenged them with a stick and they ran away like little babies. Queens, sheesh.
