"The first soldiers were local people called up for military duty in times of emergency. These temporary soldiers were commonly armed with any weapon used for hunting game and other wildlife. A common development of these weapons were wooden spears and large pieces of wood or bone. These tools were easily made since they could be crafted very easily and were an extension of weapons already used for hunting and gathering. Early troops that used these weapons were effective and needed minimum training. The club itself had very little practical use other than for combat against other humans since it was too slow and cumbersome to hunt game. These early fighters eventually became obsolete following the Neolithic Revolution, as better tools and toolworking became available. Some of these improvements included improved stoneworking and woodworking, and later the introduction of more advanced metal weapons made from bronze."
