I will note that the United States Army got a major chance to shine during The War. They brought the largest tanks, mechs, and aircraft to the various fields of battle, from reserves stockpiled for generations. They constituted the core of trained soldiers that defended Western Alliance worlds across colonized space, and they fought on more Chinese and Russian outposts and colonies than most people even knew existed. It was the Army that conducted the ground invasion and occupation of the Hyades Cluster after Alliance warships cleared the orbitals. Space Marines like the Cowboys may have gotten good press and media deals, but it was the average GI Joe who brought the heavy end of the hammer down on our enemies. Or maybe they were a Jose, a Jay, or a Jacy depending on the culture they came from. They volunteered to serve from every American State and colony, and they fought for two decades straight under alien suns to secure America’s continued survival.
