For more detailed background info,
The Squids are a team of Highly trained female soldiers of different backgrounds being used by the PMC group Pievre Armenent to test they're cybornetic enhansment ARM's, robotic arms to replace they're biological arms and legs to help pave the way for the next big step in Military hardware.
Field Scout is the teams leader, shes a quick calm thinker who hold great pride in her work. her ARMS are designed to give her body perfect blood flow and muscular endurence giving her the abilty to survay her enviornment faster and farther then any normal person can and with her terrain scouter she can plot out environmental data and give on the fly battle commands to her teamates instantly.
Scout squid and the rest of the girls are all the same rank bellow Field, she is the stealthy one of the team, going in first to try and take out as much of the opposition as she can, her and Field work the closest together since the two of them go the deepest into any enemy territory, Scout is a bit of a wild card, suffering from Psychopathic personallity issues that she has to have kept in check with medication but skills come massively in handy as her ARMS are built for enhanced strength making her capable of cutting stone like it was butter.
This covers the offensive team, eventually the defensive members of the team, Sniper and Trapper Squid.
