One more quick question! Why do units I produce sometimes usually appear at an HQ higher up the chain? It seems like I'll tell a city to produce machine guns, and then they appear at a city further back for example
Whatever a city (or tank/plane/gun factory, if you build some eventually) produces will be sent to the HQ that city is assigned to.
There has to usually be a road/railway line to this HQ.
Simplest way to usually set it up is to have all production be sent to your Supreme HQ and the distribute if from there (unless distances and train capacity is insufficient)

On the left side of the panel (bottom of the screen), where the factory icons are, there are two, one is a plain brown factory icon the other is also brown but has HQ written in yellow. Select that and you can select which town/city/factory sends it produce to which HQ. Every town/city/factory sends it produce to 'High Command' by default. Be careful, you don't want to send the entire turns' supply to a small command on a irrelevant front.
The 3 Nations War has begun ... each side is scrambling to secure its resource cities -- a tougher job for @DellieJonut 's NEW YORK PROTECTORATE out west and my eastern NIPPON empire. ... @Nathangun 's country is stuck in the middle bottom, yet his resources and cities are much close to the capital, but he might find himself with a smaller territory and a two-front war on his hands pretty soon.
