If you're building a military from scratch right now, in the modern day, then you don't necessarily need to put your SF under different branches and then throw another command down to coordinate them like the US does. A good deal of the current structure of modern militaries derives from nothing more than simple tradition and political wrangling. Newer militaries in the real-world tend to draw inspiration from other, older militaries, such as the US/UK, which means they copy these inefficiencies, but there is no practical reason to do so.
Doctrinally and strategically, there should be no need for a separate 'Marine Corps' in most militaries; they only exist now due to historical lineage and tradition. Marines were originally created as a dedicated ship-borne fighting force, back when boarding enemy ships was common and required a special skill set, and to put down mutinies by the ships' crew against the officers. Neither of those roles are of any real consequence today, and as Operation Overlord showed, properly-trained Army troops can be used for landings so long as they are provided with the necessary equipment.
