Welcome to 203X. The federal government is no more, and the once United States are now but splintered factions fighting over their own homeland. Those who were under American protection now find themselves defenseless. The Russians are rallying their EUSS friends, exploiting the chaos to export the wonders of neo-sociallist thought. Their concealed hands hold many nations in their grip. The Chinese, having abandoned their past, push their Revolution to the next, ever more brutal, stage. If they succeed, freedom will become a relic of the past. The UN Armed Coalition is assembled, in hopes to enforce the order engineered by the first world. Those who do not comply will be subdued for the greater good. There is no escaping the world war. Everyone is ready to Assault Amerika. Are you?
The Rifleman is your average GI Joe, armed with an assault rifle. As a core unit, the Commanders will make platoons of them to cover more valuable units and to fight enemy soldiers. They become a big threat in urban combat, as they can enter civilian buildings and clear hostile garrisons.
If the Riflemen are the bread of US Army, then Rocket Troopers are the butter. More expensive, they carry handheld rocket launchers that can deal serious damage to armored vehicles, aircraft and structures. They can take cover in houses for extra protection, but in doing so they lose their AA targeting.
Finally, the Scout fills the support role for the Americans. Fast, lightly armed and armored, they are excellent spotters that are able to reveal stealth units and identify hostile infiltrators. Scouts are issued carbines that are inferior to Riflemen's guns, but as the battle progresses, they can be retrofitted to keep their relevance. Just like other basic infantry, Scouts can garrison structures.
Engineers are nerds that can repair friendly buildings, crew abandoned vehicles, defuse bombs and sabotage hostile structures. They can't even throw wrenches with their noodle arms.
