Fighter/Attack. It was designed to serve both as a fighter, which attacks other airplanes, and an attack plane, which attacks ground targets.
Many propeller airplanes have variable pitch propellers, these can be set to a reverse pitch which allows the aircraft to back up on the ground and can also be used to help an aircraft slow down once it has landed on the runway. On a jet there is reverse thrust, which is a deflector(s) which when engaged forces the jet thrust forward past the outside of the jet engine. This also allows a jet to back up on the ground and can be used to slow down a jet once it has landed.
