The computer's reckless use of cavalry does not resemble the historical Indigenous tactics described here. The game's designers also appear not to have modeled land warfare closely. A cautious probe reveals concealed infantry and a medicine-man unit before they can spring an ambush. Making the enemy form a visible line removes its surprise advantage while still acknowledging the skill and capability represented by those troops.
