Soldiers are the fighting units of the game. You recruit them at the Barracks at the cost of money and time. The number of Generals you have determines the top number of Soldiers you may have.
Note: you do not kill Barbarians or have your own troops killed.
True to the Asterix comic book series, Barbarians are "scared off". And when you lose troops it is because they "run away", again because they are scared.
This may mean instead of weapons, we may level up troops through Courage.
