I think a cool name for it would be SG-Alpha, or SG-A if you're looking for a flagship team name, if you're looking for something more in the background, then you could use another Greek Character or letter. (ex. Alpha, Beta, Gamma, Delta, Epsilon, Zeta, Eta, Theta, Iota, Cappa, Lambda, Mu, Nu(I believe those are how those two are spelled), Xai, Omicron, Pai, Rho, Sigma, Tah, Upsilon, Kai, Sai, Omega)
