Re: Why is it \'bbl\' ?
"tank" comes from the first british tanks... which, to prevent the enemy from figuring out what they were, were refered to in design, and early transport as "water carriers". After all, the first ones looked like water carriers. Naturally, military quickly shortened this to "WC" the british term for a restroom... or rather, a closet with a toilet in it. The designers, engineers, military guys, and pretty much everyone else wasn't real fond of telling their loved ones they were working on a armored "WC", and as such it became refered to as a "water tank". For whatever reason, it wasn't shortened to "WT" but just "Tank".
for those of you who just have to know....
