According to the official numbers, the Clone Wars were actually really small.

I have noticed a major problem with the Canon numbers for the Clone Wars:-the Clone Army is stated to have 1.2 million clones initially, with an additional 3 million ordered later on. This is ridiculously small!The Chinese Army (present day, real life Earth) has around 2 million members./r/funny has 14 million subscribers, more than 3x the entire Clone ArmyAs the droid army would not count towards the overall dead, the entire military death count of the Clone Wars would be less than 4 million, let's say it was 4. World War 1 had a count of 11 million.It is unknown, but estimated that there are around 10,000 planets in the Republic. This means there is an average of 200 Clones per planet.-We don't have official numbers on the droid army, but Kalani says in Rebels that towards the end of the war, droids outnumbered clones 100-1. This puts the maximum size of the droid army at 400 million droids.This is less than 1/4 of the amount of views on Taylor Swift's "Blank Space", or less 1/3 of the amount of people living in China.If the CIS decided to take the Clone Wars from a different approach and entered the real world, by selling each battle droid for $10, they could not afford to buy the Star Wars franchise to rewrite themselves as the victors.[EDIT]: The numbers for both sides are way too small to be anywhere near plausible for a galactic scale war. The way this was clarified in Legends is by making the quote of "1 million units well on the way" not being in reference to clones but military units, with the number of clones being in the hundreds or more, which is still fairly small if you think about it but it's definitely a step in the right direction. I would just like clarification on this so we can get a concrete answer and properly understand the scale. via /r/StarWars http://ift.tt/2h7WYYj
