WOT - Power Leveling Guide

According to various sources on the internet, Power Leveling (PL) "can take many forms depending on the game being played, the method of leveling, and the sources of XP."  Wikipedia defines it as "the process of sustained, fast leveling".  WoWWiki defines power leveling as "the process of leveling as rapidly as possible with the least amount of play time."  While all three definitions can be applied the WoT, I think the last definition captures the essence of power leveling regardless of the game being played.  As someone who has played various MMORPGs for several years now, I can confirm that I have power leveled many characters in all of them.  And World of Tanks is no different.  Well.... mostly!
