Until the invention of firearms, the bow and arrow was the weapon of choice for warfare throughout most of the world.  In Hollywood movies, I think it's crossbows and the longbow that get most of the attention (Braveheart et al), but in this video Iza Privezenceva, a young Russian woman, shows how a shorter bow could be wielded as the forerunner of a machine gun.

Imagine being a peasant pressed into the king's service, being provided with a long pointed stick and perhaps a leather shield, and facing a line of these archers...

Question for someone - which arm needs to be stronger in a professional archer - the one holding the bow, or the one drawing the arrow?
