Artillary training has been going on at the Camp Williams army
installation in Utah (About 30 miles south of Salt Lake City). The
blasts have been audible throughout Utah County where I live.

Last evening on the Salt Lake Fox News affiliate, one of the reporters
was there at the army base reporting just what's been going on. He
described the training and the projectiles that were being fired.

Everything is calculated by computer - EXCEPT - all calculations are
double checked by hand on a slide rule, and the reporter referred to
them as such! (So the computer's calculations aren't gospel, and they
are checked by hand!)

While the news video did not show what the slide rule looks like, it
showed the soldiers using them. The SRs in use do not appear to be
conventional - they are rather large! By appearance, they are
definately much larger than a typical 10" rule both in length and width.

Anyone have any idea what they use?
