Hi. I have just started getting back into generals and want to add a few units and structures like the UN Humvees and Oil derricks as well as some others to USA build queues. UN Humvees are known as Humvee1 in the game files. I only have original genereals and don't have zero hour. I also have final big file extractor since I have already been changing campaign maps in worldbuilder. This is becoming a hobby and would really like to learn how to do mods like this.
