I'm not surprised. Warfare tend to favor the asymmetrical approach. You don't really want to send tanks to destroy other tanks. The most prefarably option would be to send planes or other aircraft to destroy tanks, since the tanks have no considerable means of shooting back. A lot of rock, paper scissors going on.

@elljay3453 : Yeah, the technology wasn't there yet. But they clearly wanted to be able to engage the tanks with aircraft. And technology certainly moved in that direction overtime.

It's not that hard to convert in your head. I usually think like this: 1 inch equals 2,5 centimeters. It's not exactly 2,5 centimeters but it'll give you an inkling of what caliber is being spoken about. So if they say .50 cal. Then that is 0.50 parts of one inch i.e half an inch. 2,5 divided by 2 equals 1,25 centimeters. But there is no such thing as a 1,25 cm caliber in metric. But there is a famous 12,7mm. So a .50 must be 12,7mm (although this only concern the measurement, it doesn't account for powder load or cartridge length) With feet I usually think that there is three feet in one meter. Once again it's not an exact conversion, but it's close enough to get the gist of what sort of measurement is being talked about.
