This is a strange case. One which involves "realistic" numbers having been established in the EU on one side of a war, and extremely minimalistic numbers established on the opposing side. The war is the Clone Wars. The sides are Droids versus Clones. The problem: According to EU the clones were outnumbered by obscene amounts (to be discussed below).

Based on calculations derived from the Geonosis Foundry output, the CIS could effectively double its size in less than a month, and perhaps as little as a day. This is supported by EU figures, which state that, by ROTS, the CIS had quintillions of droids. A quintillion is 1E18, or 1,000,000,000,000,000,000. That's huge.

For the Clones we have the ambiguous "We have 200,000 units ready, with a million more well on the way," quote from AOTC. Problem: What defines a unit? Is a unit one trooper? Is it one squad? One Platoon? One Division? One Legion? It isn't defined.

Well logic would tell us it cannot be a single clone. 1.2 million clones isn't nearly enough to fight a galactic war. Unfortunately, 1.2 million clones is what EU decided to go with. Maybe LFL can't understand the vastness of the galxy, or the fact that the Soviet Union lost more than 1.2 million troops in World War II on a single planet.

But wait. There's hope. LFL stated that they realized that the 1.2 million clones was foolish (even with the AOTC ITW attempting a retconn by saying millions more clones were nearly ready at other Kaminoan facilities), and would be correcting the figure in later publications or works.

Then, in just the past week or so, Star Wars Insider had a feature about the Grand Army of the Republic, written by the esteemed Karen Traviss and Ryan Kaufman. Alright! I thought, this will fix that crummy 1.2 million!

Sadly, I saw that the article not only supported the original output being 1.2 million, but capped the number of clones at 3.2 million (or maybe 6.2 million depending on how you interpret the article). I was suprised to say the least. Adding on a few million clones isn't gong to make any amount of difference against quadrillions or quintillions of enemies. The authors and LFL soon recanted, saying that there would never be a difinitive publication on the number of clones (to which I wonder; "then why put that info in the article at all?"), effectively backwheeling and leaving us in the dark. But the number was published, and anyone reading it can tell that the original intention was for the entire Grand Army of the Republic to number in the low millions. Not very Grand is it? The US Army in WWI had as many men.

It's nonsense. It's impossible. Minimalists can scream all they want about how awesome the Clones were, and how they were only special forces, and how droids suck and other such foolishness. But it is practically impossible for 3.2 million to defeat a few hundred million, let alone quadrillions or quintillions. And this isn't even mentioning the fact that Clones man guns on capital ships and fly most of the fighters. 3.2 million clones were probably used up manning guns and fighters at the Battle of Coruscant.

But to offer some cold hard logic, let's generously assume that the CIS had only 2 Quadrillion. That's 2,000,000,000,000,000. Alright so we have a gross underestimation and extreme lower limit on the number of droids in the CIS. Then let's look at the "Grand Army of the Republic"; 3,200,000. Looks kinda puny in comparison huh? Well, it is.

2 quadrillion diided by 3.2 million gives us 666.67 million!!

You know what that means? Each clone trooper will have to kill 6.6 MILLION droids in order to break even, and the clones cannot suffer any casualties. Well you tell me, do the films support the clones defeating the droids by a ratio of 666,666,667:1? Nope. Does EU? Nope. Even the exaggerated Clone Wars Cartoons show inadequate ratios. The SWI article itself states that clones killed droids in a ration of 200:1. That may be feasible with our given information, but it's hardly going to help the clone army defeat an enemy with forces 6.6 million times larger!

Think about it, every single clone trooper would have to mop the floor with the entire population of United States 2.5 TIMES single-handedly and not one of them could die.

So. This is yet another case of EU minimalism. This one has not been fixed (and if LFL is to be believed) will never be.

Maybe 3.2 million Divisions or Legions of clones might be sufficient. But 3.2 million clones would not be able to capture and hold a single world, let alone go on the offensive against a force that out numbers it 6.6 million to One.
