re: #487 wrenchwench

If I were to consult Mr. w, it would be navy rules all the way.

He was a supply and payroll clerk, because he typed so well when he signed up.

I suppose that depends on which part of the Navy, in aviation it was not so:

An A-6
An AN/ARC-59 (pronounced “an A-N arc fifty-nine,” an airborne UHF radio set)
NAVAIRSYSCOM (there is only one Naval Air Systems Command, so “a” or “an” do not apply)
a missilex (missile exercise)
an ENCOM drill (emissions security, or control of broadcasts)
