Arco San Louis sits at a confluence of borders, rivers, and nations within the Atlantic Federation. The city, built approximately 70 miles from the site of Old St. Louis is a model of Cosmic Era efficiency. The Central Arco rises and impressive 1.75 kilometers from the ground, with another 1000 feet of aerials and antenna rising from it's core spire. A shining brushed steel edifice, it's fluer de lis picked out in gold paint on each of it's four primary faces is 300 meters tall. Around the feet of the arco the city rises up, half a dozen demi-arcos, almost all owned by corps and megacorps, and heavily involved in industrial applications. Those buildings are in turn nestled up against high rises built up from an elevated false ground level of clean streets with efficient public transportation, greenspace, and all the amenities that make Arco San Louis one of the top ten desirable cities in North America, and the 11th nicest city in the Atlantic Federation. Beneath the false floor the real ground level, in perpetual shadow of the city above it, and the geofront foundations that hold everything up 'cover up' the cities gang problems, it's urban poor who congregate in the underground housing projects, and the debris littered subterranean boulevards that connect the undercity to the economically repressed rim of the city. There are no favelas, no centuries old buildings that have been turned into massive tenements, that was all abandoned and left behind when Arco San Louis broke away from Old St. Louis.
The Mechadrome for the city is located on the western side, and it houses a full mecha battalion, 40 active machines in 8 squads. There is also helocraft support in the form of both gunships and troop carriers that can deploy power armor troopers as the need arises. The city itself retains the services of not one, but two Self Propelled Turrets, the Spirit of St. Louis (a first gen autocannon armed crawler) and Kingshammer (a last gen rail gun armed crawler)
The city retains such a large garrison as it is a rarity, Arco San Louis is a free city, not attached to any of the nations surrounding it, and the garrison it has is drawn half from locals, and half from units rotated in through the Atlantic Federation's Armed Forces. The city, long tired of constant fighting between the Rocky Mountain Republic, the Republic of Texas, the Republic of the Great Lakes and even a brief occupation by the Confederation of Southern States, declared its independent state, used mercenary forces to repel the nationalist forces, and requested recognition and protection from the Federation governing council. Since then, the city has been a hotspot of activity. Free Cities draw in megacorps, and the city's security contracts are lucrative and draw in mercenary companies and security companies as well. The mix of Federation troops, mercenary troops, and Free City Troops makes things interesting.
It doesn't help that even Amerikka Command wants a piece of the city.
