Fire Support Marine

“Serve as the eyes of the artillery, calling and adjusting fire from forward positions to support Marines in contact. Fire support Marines work at the intersection of infantry and fires, providing the lethal reach that turns the tide of engagements.”

You are standing or lying on a piece of terrain that the enemy also wants, looking through a laser rangefinder or a LLDR at things that are trying to kill your fellow Marines, and you are doing math. Fast math. Grid math, observer-target line math, adjustment math, translating what your eyes see and your instruments measure into a fire mission that puts steel on a target that is probably close enough to your own position that the margin for computational error is measured in single-digit meters. The moral weight of this job is not theoretical — you are the human being who authorizes fires. That responsibility shapes you. The training at FSSC is rigorous for exactly this reason. In garrison, you're doing FO certifications, JTAC pre-qualifications, and scheming to get more range time. The relationships you build with the grunt platoons you support are the strongest in the Marine Corps. They will carry you across terrain. You will bring the thunder.
