Please oh please help me, beginner and need guidance please,united kingdom of ottelo mara

Certain products that I want to purchase I'm having difficult time with. For example, I want to buy precision bombers, it tells me buy it directly or buy it on a space station. What does buy it directly mean? Directly from whom? Where? And I can't find anything on space stations. I don't even have a space center. Do they even have bombers?
My second question.....lots of my weapons are inactive. It says I have a shortage of officers and personnel. How do I increase my personnel numbers to activate my inactive weapons. Almost 70% of my weapons are inactive. Please help me.

First, precision bombers are no longer traded freely on the open market; you must either manufacture them yourself, or buy them from a space station when they are available. They usually aren't available unless you make a deal with another player to sell you the bombers. Then you have to pay 50 GC per month to do business on a space station, even if you only make 1 or 2 trades per month. Then you must buy shuttles with GC, to freight the bombers from the space station to your home base, which is a space center that you have to construct.This route is definitely not worth it, as you end up spending hundreds of GCs to get maybe a few hundred precision bombers. Unless expense is no object, then by all means do it, at least you will have a bomber squadron...
Direct trade: you can direct-trade between your own countries; produce the bombers in one country and sell them to another. You still have to make the bombers. Bomber corps almost always operate a
