An overview of the beginning of the production tech tree.

Military technologies improve the army and navy. These consist of a mix of new weapon technologies, doctrines, and ways of organizing the servicemen and officers. Some techs will establish a more reliable supply of manpower and causes fewer provinces to be lost when territory must be yielded to the enemy. The naval part of the tree is mostly dedicated to the invention of new ship types, but also includes a few new naval strategies that unlock or improve the effectiveness of certain naval orders as well as upgrades to civilian ports to improve the country's supply network and trade capacity.
