[Star Wars] How were the ewoks able to defeat the stormtroopers on Endor?

Their arrows don't seem able to actually do any damage to the Stormtroopers armour.

The Ewok species is perhaps one of the more dangerous forces in the less-traveled sectors of the galaxy. 

Consider, first, their intellect. Barely into their Stone Age, they have invented rudimentary flying machines and siege weapons, also harnessing the powers of the arboreal habit in which they thrive. They seem to have a natural inclination for advanced technology, as well - theft of speeder bikes was not uncommon, and if word from communications operators overhead during the Battle of Endor is to be believed, they even commandeered a scout walker to great effect. 

More dangerous than their minds are their bodies. Whomever selected their homeworld as a suitable base failed to properly quantify the weight-to-muscle ratio of the average Ewok; indeed, simply *looking* at an Ewok can make it difficult to gauge their strength. Harmless by appearance, the Ewok's limbs are packed so thoroughly with muscle that they have limited flexibility in their joints. They are slow, but easily as strong as a Wookiee, and more lethal for their innocuous demeanor. 

Perhaps a greater threat to the Imperial forces on Endor during the battle was the complete lack of competence of the command system - a legion if troops wearing *plastoid* armor won't fare very well against the sort of enemy that can put an arrow through a tree. The hubris of the command not to fire-bomb the forest once the shield bunker was penetrated proved disastrous for the Empire. 

There is good reason that the sentry moon of Endor has been labeled as a Hazard Level VI. People go to the Ewoks looking for teddy bears; what they forget is that the Ewoks **are** bears... hyperintelligent, zealous, all-muscled **bears.**
