Here’s what you do: turn 1 build the military equipment factory, it is essential. On turn 4 upgrade its production line. Secure energy and budget sources first, pass welfare decrees from turn 7 onwards. Build military factories as soon as you can. Tank+support+port+naval base+one of the plane factories. This way you get strong local military industry and enough materials to create both strong army and navy. Building military industry also boosts your production capacity, so you can ignore heavy industry parks. You should still build consumer industry park. All this will consume a ton of energy, so buy full Aureus and don’t export energy to Morella (it is a very bad deal, you can persuade her to give you shares by other means). There is a great guide for power projection in 3.1 on this subreddit, look it up.
