Infantry experience bonus

[FactionHeir]

Quick question really,

What is the parameter for making a building give a bonus to all infantry trained?
I know the codes for archers, cavalry and knights, but the game doesn't seem to recognize heavy_infantry, light_infantry and infantry.

Thanks for reading.

There is none, only recruits_exp_bonus which will increase it for all
