They give typically give various military-related bonuses and modifiers as well as unlock new unit abilities, unique combat tactics, and special unit types, often promoting the use of different unit compositions and strategies, though some traditions can also have various economic effects such as creating pops, constructing buildings, giving economic modifiers, or granting innovations and province investments.

Military tradition types
There are seven different military traditions groups in the world, each tied to one or more culture groups. Each country starts with access to at least one military tradition group based on its primary culture, with a few countries also starting with access to one or more tradition trees outside of their groups. Every tradition group contains at least one tradition to that unlocks access to another military tradition group; adopting these traditions always requires that the country has an integrated culture in one of the relevant culture groups which has at least either 500 pops or 1/4 of the pops of the primary culture. By working its way through these traditions to embrace foreign influence, it is possible for every country to eventually get access to every tradition group (and adopt every tradition) with sufficient military experience and pops of the required culture groups.
