As far as how many level 9 inf a tank can crush before it dies, that can be found out with the following formula:
=(E7*9)/(C9*9)
or 6.1578947368421
It is the same. A unit's attack and defense value does not change because it is attacking or defending.
There is actually a slight benefit for defending units.
- The attack level is multiplied by a random factor. The random factor has a slightly larger range that dips lower for an attacking unit than for a defending unit. Therefore, overall, defending units have a slight advantage, but it's not a definite advantage.
