Perks

Perks are special skill boosts that the player can select for units as they increase in rank. Each of the Unit Types has their own list of perks though some perks, such as Discipline Training or Marksman Training, can be found in the lists of multiple Unit Types.

Please note that some of the perks in the un-modded game have bugs that prevent the listed skill boosts from working correctly. Those buggy boosts are noted on the Perk.
