It's hard to say what you'd need to do to your truck to match the other one without us seeing them in person, side-by-side. Maybe the other truck had been repainted very well. Maybe it had been color sanded and buffed to perfection. Maybe the factory paint job is better.
Dark colors display a deep gloss better than light colors, same with solid colors instead of metallics. You say you have a "Marine Corps" green. Is it dark green metallic? If so, Ford calls it Dark Highland Green (one of their most famous colors). That color theoretically should be able to shine up very nicely if polished to perfection. What could hold it back is orange peel, swirl marks, oxidation, buffer marks, or any number of surface defects.
This is a hard question to answer accurately without evaluating the truck personally. I wish I could be of more help.
