The key words are "up to." Probably one unarmed guardsman handing out bilingual "Welcome to the U.S." pamphlets with maps to the nearest jobs "Americans won't do."
My buddy is in the Virginia Guard. He and his company spent six months camped out at the Tucson Double Tree Hotel, doing largely nothing during the week, but driving over into Mexico on weekends to party it up with the local senoritas. His deployment was a complete joke, and I suspect that his story is the rule rather than the exception for other Guard units currently down on the border, if any are still there.
