The Lancers

Simple+

English RU

... the vampires fought fiercely. Judging by the course of the battle, Sir Ronald made the right decision, although not very ethically ambiguous.
Suddenly, new soldiers joined the Umbert’s ranks - has he really got an ace up his sleeve? Lancers presented the fresh forces, which made Sir Ronald’s position increasingly difficult, lancers could attack two soldiers at once with their long spears. Something needed to be done with that…

It seems that the Warrior, Knight, Defender and Vampire are not enough to win the battle. Let's add one more powerful unit type - the Lancer.
Lancer should be the subclass of the Warrior class and should attack in a specific way - when he hits the other unit, he also deals a 50% of the deal damage to the enemy unit, standing behind the firstly assaulted one (enemy defense makes the deal damage value lower - consider this).
The basic parameters of the Lancer:
health = 50
attack = 6

example

Example:

chuck = Warrior()
bruce = Warrior()
carl = Knight()
dave = Warrior()
mark = Warrior()
bob = Defender()
mike = Knight()
rog = Warrior()
lancelot = Defender()
eric = Vampire()
adam = Vampire()
richard = Defender()
ogre = Warrior()
freelancer = Lancer()
vampire = Vampire()

fight(chuck, bruce) == True
fight(dave, carl) == False
chuck.is_alive == True
bruce.is_alive == False
carl.is_alive == True
dave.is_alive == False
fight(carl, mark) == False
carl.is_alive == False
fight(bob, mike) == False
fight(lancelot, rog) == True
fight(eric, richard) == False
fight(ogre, adam) == True
fight(freelancer, vampire) == True
freelancer.is_alive == True

my_army = Army()
my_army.add_units(Defender, 2)
my_army.add_units(Vampire, 2)
my_army.add_units(Lancer, 4)
my_army.add_units(Warrior, 1)
    
enemy_army = Army()
enemy_army.add_units(Warrior, 2)
enemy_army.add_units(Lancer, 2)
enemy_army.add_units(Defender, 2)
enemy_army.add_units(Vampire, 3)

army_3 = Army()
army_3.add_units(Warrior, 1)
army_3.add_units(Lancer, 1)
army_3.add_units(Defender, 2)

army_4 = Army()
army_4.add_units(Vampire, 3)
army_4.add_units(Warrior, 1)
army_4.add_units(Lancer, 2)

battle = Battle()

battle.fight(my_army, enemy_army) == True
battle.fight(army_3, army_4) == False
