You will receive Stat Points each time you increase a Unit's Rank. Stat Points are a brand new Resource that can be allocated to increase a Unit’s Offense or Defense.
Each allocated Stat Point grants a one-percent Bonus to a chosen statistic. You can reallocate Stat Points at any time using a Stat Point Redistributor.
NOTE: Stat Points can only be applied to the Unit that earned them. For example, if you receive Stat Points for upgrading your Paratrooper, you must apply those Stat Points to Paratrooper Offense or Defense statistics.
