When tractors were first developed, they used enormous steam engines that were notoriously unreliable and hard to maintain. These were phased out around the turn with the twentieth century and substituted for internal combustion engines which were smaller though powerful and ran on a number of fuels including kerosene, ethanol and gasoline.

Before going into battle a soldier needs to prepare. To wear the proper armour and get hold of a shield and sword. The armour protects from harm as well as the sword kills the not so good guy.
