Angola

Angola is a Satellite State of China and a member of the Comintern Pact. It is unfortunately the only communist country in Africa. However you can conquer all of Southern Africa and East Africa under Chinese Rule.

Technology
With lots of hills and mountains there is likely very little need for armour. Focus on infantry and supporting Doctrines and Industrial technologies.

Distribution of Leadership Surprisingly strong at 9+ Leadership to distribute. This can of course increase with proper research of Education et c.

I recommend: 7 Leadership allocated for research 2 Leadership for Spies to get domestic spies up to 10 to raise Unity then shift these 2 to produce Officers will have you in a comparatively strong position around mid-1937 when war with Japan is likely.

Diplomacy
Alliances You start allied with China.

Decisions Accept the Call to Arms or not when Japan and China go to war.

Politics
Ministers Laws Political Parties

Intelligence
Get domestic spies up to 10. Set them to work raising National Unity to allow more efficient Laws and resist potential defeats in wars.

Maybe spend some time hunting foreign spies too if you are feeling happy with your National Unity.

Economy
Trading Not extremely good or bad. Trade Metal from Libya. Trade Rares from the United Arab Republic. This should keep you afloat for quite a while.

Industrial Production Once again, surprisingly strong industrial base, starting out at 28 IC. Greatly improves when war starts.

Military
Army Lots of infantry divisions and militia at start. Very few commanders, these do not increase when war happens as far as I can see. All divisions contain 2 brigades only. Might need strengthening to ensure proper power.

Navy A single air carrier at start.

Air Force A single Airship wing at start.

War
War with Ethiopia the first Nation of the Tokyo-Tehran Pact you have to deal with. Ethiopia will try to create a way to get to create a secretive trade route out of Saudi Arabian eyes and southwest Africa is a sneaky trade point however they will have to take on you.  War with Persia it's recommend if you want to create a Communist African Empire overseas in the Pacific. Plus China will have you do this in which AI Angolia will do anyway, but you will have to deal with Persia since they rule over Mozambique and Tanzania.
