North America Sector
Estimated Population: ~42,000,000
The North America Sector encompasses the majority of what was once Canada and the continental United States. It is for the most part under the sole control of the Army of the Southern Cross. Monument City, site of the headquarters of the Army of the Southern Cross is located in the North America Sector.
- Monument City: the largest and most advance city on the continent, Monument City is the home and world headquarters of the Army of the Southern Cross. The city hosts the majority of the Southern Cross forces and has the second largest concentration of Robotechnology manufacturing and research facilities on the planet. South of Monument City is the former site of New Macross City. The city was abandoned and buried after the destruction of the SDF-1 by rogue Zentraedi and the area is now strictly off-limits.
 - Yellowstone City: former site of the Robotech Defense Force World Headquarters, this modern city is still home to one of the three remaining active RDF bases left on Earth. While the old RDF training academy has been shut down, the mecha repair center is still in operation to support the remaining RDF forces.
 - Nunavut Base: the northernmost Southern Cross base on the continent, this base is home to a large contingent of CWOS troopers.
 - New Detroit: the eastern stronghold of the North American Sector. This city sits on the Great Lakes near the site of the old city of Sault Ste Marie, Michigan.
 - Denver: the rebuilt city of Denver is only a shadow of its former self, but is home to a hardy and dedicated populace determined to make this mountain town great again.
 - New York City: though the city was thoroughly devastated by the Zentraedi, the surviving New Yorkers were too stubborn to leave and are determined to rebuild. Miraculously the Statue of Liberty survived the alien onslaught and stands proudly over the ruins of the city, offering hope to its residents.
 - Fort Baker: a major Southern Cross base. Its forces consist primarily of ground-based forces that spend much of their time patrolling the region near the independent York Barony and Arkansas Protectorate.
 - Phoenix: appropriately enough, this city has been reborn from its own ashes. The major aqueduct network constructed to provide the old city with water is still intact and has enabled the populace to rebuild.
 - New Albuquerque: a newly constructed metropolis with state of the art technology and a strong manufacturing base. The city is also home to a large oil drilling and refining industry. New Albuquerque is the home of a major Southern Cross base (actually an RDF base the ASC took control of) which is responsible for patrolling the western wastelands as well as the area that was once the southwest of the United States. The base is also in a position to provide support to Central and South America.
 - New Orleans: this city suffered more damage from flooding that resulted from the Zentraedi assault than from the assault itself. The survivors moved into the parts of the city that were still above water and immediately began to rebuild. Though nominally associated with the UEG, the local government is (in true Louisiana tradition) thoroughly corrupt and has regular dealings with both the nearby Arkansas Protectorate and the York Barony and also enjoys strong ties with the Merchant Republic.
 - Fokker Field: a former RDF base located near the ruins of the old Cape Canaveral space launch facility, this base is now home to several TAF squadrons assigned to patrol the Caribbean and much of the Atlantic seaboard.
 
Quebec Quadrant
Estimated Population: ~4,500,000
With the breakdown of the UWG in the wake of the First Robotech War, Francophone separatists finally realized their dream of an independent Quebec. Of course, the majority of the industrial and technological base of the region was lost in the Zentraedi assault. Reconstruction was spotty and the bulk of the populace lives in and around the capital of New Quebec City. Recent discoveries of mineral resources has given the Quebec Quadrant much-needed wealth to spur their rebuilding efforts. The Free Nation of Quebec is pacifistic, but strongly independent and does not actively aid or cooperate with the UEG or ASC. They often trade with the York Barony for industrial products, but with their new mineral wealth Quebec has begun making overtures to the Merchant Republic to build up their military defense forces.
- New Quebec City: with the major cities of old Quebec annihilated in the Zentraedi planetary assault, the founders of the Free Nation of Quebec selected a spot near the center of the old province as their new capital. The city started as something akin to an old pioneer fort but with the newly discovered mineral wealth of the Quadrant allowing for the import of industrial and manufacturing goods the city has modernized itself.
 
York Barony
Estimated Population: ~1,000,000
This self-proclaimed Barony rejected all ties to the UEG and became a haven for humans opposed to the RDF's efforts to integrate the Zentraedi into Earth society. They have a strong manufacturing and military base, but little agriculture resources. In order to feed its populace York used to trade with Quebec, but more recently they have opened trade with the Arkansas Protectorate. Despite the destruction of most of the rogue Zentraedi on Earth and the departure of the loyal Zentraedi forces with the REF, the York Barony remains vehemently opposed to the Unified Earth Government and the Army of the Southern Cross.
Arkansas Protectorate
Estimated Population: ~3,000,000
The Arkansas Protectorate came into being shortly after the end of the First Robotech War. A group of Zentraedi conquered the area but, much to their surprise the conquerors discovered that the humans were willing to accept Zentraedi rule. So long as they were kept safe from other rogue Zentraedi, and from human bandits and raiders, the populace didn't much care who was in charge. When the Malcontent Uprisings began, many of the Zentraedi in the Arkansas Protectorate left to join the Malcontent forces. Near the end of the Uprisings, the nearby York Barony launched an invasion to "liberate" the Protectorate from its alien overlords. The remaining Zentraedi were wiped out and the Arkansas Protectorate turned over to human rulers. Since their military had been Zentraedi, the Protectorate was now dependent on York for defense. Primarily an agricultural center, the Arkansas Protectorate is now the major food source for the York Barony and trades with them almost exclusively for industrial and military goods. The Southern Cross is keeping a close eye on the situation in the Arkansas Protectorate as there is every indication it will merge with the York Barony, forming a powerful political and military entity on the Army's own doorstep.
- Little Rock: the rebuilt city of Little Rock serves as the capital of the Arkansas Protectorate. There are several buildings in the city designed for full-size Zentraedi, but since the aliens were driven out these buildings have been demolished or converted for military or industrial use. The remainder of the Protectorate consists mainly of small farming communities.
 
Mexico Quadrant
Estimated Population: ~7,000,000
The Mexico Quadrant is made up of the old country of Mexico and the remainder of Central America. The area was largely unaffected by the Zentraedi assault and is home to a large population. The reconstruction efforts in this area of the world focused more on modernizing the existing infrastructure than on rebuilding. The overall technological level is about equal to the late-twentieth century United States, just before the Global Civil War. The Mexico Quadrant is a staunch ally of the United Earth Government.
- Mexico City: a sprawling metropolis and home to a large percentage of the Quadrant's populace. The city reflects both the good and bad in humanity. It is a thoroughly modern city with all the amenities and is a favorite recreation spot, but the city is also home to poverty, vice, and corruption. Mexico City is home to a large RDF base (one of three left on Earth), which is shared with the Southern Cross. The base's forces are responsible for the patrol of the Mexico Quadrant and the Caribbean.
 - >Yucatan Base: a major base for the Southern Cross' Jungle Squad army.
 - Panama City (Panama Canal Zone): the canal is the site of a medium-sized ASC base responsible for protecting the canal zone. A large city has grown out of the ruins of Panama City in response to the presence of the base, and due to the continuing importance of the canal.
 
Cuba (Cuban Quadrant)
Estimated Population: ~500,000
Cuba has become a major industrial manufacturing center for North America. It is fairly advanced technologically and is home to several small ASC outposts as well as serving as a port for naval forces patrolling the Atlantic. The Quadrant also includes Haiti, Jamaica, Puerto Rico and the Virgin Islands. The other islands are primarily agricultural centers. The Cuban Quadrant is allied with the United Earth Government and the Southern Cross.
