There are 2 different branches of T.A.S.L.: Sun Devil, and Red Lightning.
Sun Devil requires more training then Red Lightning. Sun Devil is for those who want to look more professional. Red Lightning are for those who want nothing else but to go out and play. Sun Devil requires PT(physical training), markmenship tests at short, medium, and long ranges, and is considered the more elite branch of the team. Red Lightning will still require some basic tactics such as stealthy movement, and strategies, but not to the extent of Sun Devil.
