[Rain Man]

I just bought a copy of "The Military Balance", which is published by the International Institute of Strategic Studies. This book contains the entire known inventory of every military in the world, including troops, equipment, planes, etc. It's probably the best reference book in the history of the world.

Poll coming.

As a bonus question, rank the above countries from 1st through 13th in terms of the number of Main Battle Tanks they own. I'll pass along hints about the number that each guesser gets right.
