How does Squad work? Well it's complicated, but at its core it is Aaron's baby. It's been decades worth of blood, sweat, and tears... as well as pretty much every spare penny of pay that Vought ever gave him. Both his pay for the firefighting and supe stuff, as well as the money that Vought offered him if he was willing to do... adult content.
Initially everything started when Vought was trying to branch out into rescue work as opposed to crime fighting. They had done auditions to see about putting a supe into a firehouse, and Aaron had managed to get the position (as well as some work in Vought's... adult industry) despite the fact that he was late for his interview and nearly missed it (which is a story for another time) Aaron has since assembled the first Squad, and it has grown quite dramatically, to the point where they have an entire campus that includes the main building, as well as lots of land that features training grounds for everything from search and rescue, to horseback riding. The biggest secret to their success is a supe Aaron met early on named Pollyanna. Her ability is to scan the minds of everyone she makes eye contact with and judge their intentions, as well as if they are lying. Polly helps them filter their applicants and keep unsavoury people from getting accepted into Squad... well that and the fact that every single member of Squad has to go to mandatory monthly therapy sessions, even Aaron. He knows first-hand how many supes deal with supercharged mental illness, and the work they do can be incredibly traumatizing. One of the things they have that Aaron is proud of is the Junior Squad, which allows young supes a place to be kids and helps teach them how to control their powers. They also offer training for other supes... not that people usually take them up on it. They get funding from Vought, and have a similar framework to things like the Starlight House, but Aaron is incredibly careful with the amount of control Vought has. Basically Vought has the license for certain marketing things, and they get good publicity because Squad supe teams work in disaster relief, firefighting, and rescue ops... but Aaron makes sure that he has the final say, and has everything looked over by his sister Anna-Mae, who is a damn good contract lawyer. Squad also gets funding from various other sources, and functions as a non-profit. Squad is definitely not seen as being glamorous, especially not by the high ranking teams at Vought proper. They don't get the same kind of glory, because their stuff isn't always flashy and they refuse to do fake calls. But they're absolutely vital for cleanup and for emergency services, working side by side with local firefighters and medics and helping keep people safe. Unfortunately, Aaron, and the rest of Squad, do not always get along with the rest of Vought. While on call Aaron is "Chief" and he does not respond well to the adult supes with delusions of godhood who can't control their powers well enough to avoid casualties that should not have happened... or the ones who don't care who they hurt. It doesn't matter if someone's a F-rank supe no one knows about, or if they're one of the Seven, they better not try to tell his people what to do. If they don't have the right training, then they're not in charge, and he won't let their need for a photo op get in the way of doing the job right.
