I have 24 divisions of medium tanks spread thru each army, and I have one army solely consisting of Marines. The bulk of my army's are about 15,000 men strong with artillery and infantry spam and a few support companies. I started a civil war that lasted 2 years to take power, with me being pushed to the brink of loss numerous times, I've conquered the entirety of central, and South America excluding the possessions of the European powers and I'm in the process of taking the Caribbean, I've gone for the Mass Assault doctrine for the hearty manpower increase, and I have 6.7 million unused manpower.
It's 1942 and I'm really liking how this game is going so far.
