The Battle Tank is the heavy unit of the Modern Era. To train this unit, a Battle Tank Factory is required. It can also be received by completing the Defending the Empire Story Quest.
The Battle Tank is essentially a Tank upgraded in basically everything: gaining 15 attack points, 5 defense points, 1 range point and 6 movement points.
Their attack and defense bonuses against Fast and Ranged Units are also upgraded by 5 points on each aspect.
As a heavy unit, it is the first time they have more range and movement than the corresponding ranged unit of their age. This makes the Battle Tank a much more maneuverable unit and stronger in most situations, compared to the old idea of being slow and tough.
History[]
Modern Tanks revolutionized warfare. It combines the shooting range of a stationary cannon with the mobility of a tank. Additionally the well shielded cabin inside the tank provides a decent defense against infantry.
Against Same Age Units[]
Paratrooper[]
The Battle Tank completely dominates the Paratrooper due to its bonus of 55 attack and defense versus ranged units. Even when the Paratrooper hides in the woods, the Battle Tank typically has enough mobility to still attack on the next round.
Mechanized Infantry[]
The Battle Tank completely dominates the Mechanized Infantry or Champion due its large bonus of 55 on attack and defense. Both units have good mobility and range, but the BT has far more firepower and defense with their bonuses.
Bazooka Team[]
The Battle Tank is extremely weak when fighting the Bazooka Team, predominantly due to Bazooka Team’s bonuses as well as their high attack and defense if Dug-In is counted too. However, due to their lack of mobility and range, it should generally be easy to avoid them, but if the BT engages in combat with them, they will have a very hard time indeed.
Mechanized Artillery[]
The Battle Tank is rather weak against the Mechanized Artillery, due to the Artillery having much greater range along with a bonus against heavy units. However, the Battle Tank does have a better attack, defense, movement and range, so it may not be as weak, but the Mechanized Artillery will still have the upper hand.
