With proper training, discipline & trigger control FA gives the user a few more options. Single shot for "precision" work, hit your target with two or three rounds (ups the chances of instantly neutralizing the target (controlled burst)) or laying down suppressive fire during fire and maneuver.
I agree with Chet. Having a
Lingenfelter (sp?) 650 HP Corvette or a
Hennessey Venom 800 (HP) Viper isn't necessary but they give you that extra you can use if needed and I'm sure they would be a hell of a lot of fun cruising the Blvd on Fri/Sat nights.
