0306 vs 0322
Infantry Weapons Officer (USMC) vs Reconnaissance Sniper (USMC)
Two Marines in the chow hall: one smells like the field, the other like hydraulic fluid. Both think they have it worse. Both are right.
After-action review of two careers served simultaneously in the same military. 0306 reports: some Gunners are integrated into planning from the start; others spend their time at the range running qualification courses because that's what the command defaults to. You are an advisor, not a commander — influence without authority can be frustrating when you see tactical decisions made poorly. 0322 reports: the old 0317 scout snipers were infantry Marines who went to sniper school; 0322s are recon Marines who add sniping to their already deep skill set. Then you compete for a Recon Sniper billet and complete the sniper course through the Reconnaissance Training Company. Lessons learned: the military contains multitudes, and most of them were not in the brief. Same military-industrial complex, different floors.

Recruiter vs. Reality
The pitch versus what people who actually did the job report back.
“The Marine Gunner is the battalion's walking weapons encyclopedia — the Chief Warrant Officer who knows every infantry weapons system in the inventory cold. Machine guns, mortars, rockets, anti-armor, breaching equipment: the Gunner advises the battalion commander on how to employ all of it with maximum effect. This is not a command billet — it's a technical authority billet. When the battalion needs to know whether to use a SMAW or an AT4, what mortar registration looks like in an urban canyon, or how to set up an FPL, the Gunner is who they ask. If you have years of infantry experience and want to spend your warrant officer career being the unit's deepest tactical expert, this is the path.”
The Gunner is respected but can also be underutilized — your value depends entirely on whether the battalion commander and S3 know how to use you. Some Gunners are integrated into planning from the start; others spend their time at the range running qualification courses because that's what the command defaults to. You are an advisor, not a commander — influence without authority can be frustrating when you see tactical decisions made poorly. The warrant officer track in the Marines is narrower than the Army's; promotion opportunities and follow-on billet options are limited. On the upside: if you find a good battalion, the Gunner billet is one of the most intellectually satisfying in the infantry — you get to be the person who actually knows how all the weapons work and why.
“You'll combine two of the most elite skillsets in the Marine Corps — reconnaissance and precision marksmanship. As a Recon Sniper, you're the eyes of the MEF with the ability to reach out and touch targets at extreme range. You'll be at the cutting edge of Force Design 2030.”
You need to be a 0321 Recon Marine first — which means surviving BRC. Then you compete for a Recon Sniper billet and complete the sniper course through the Reconnaissance Training Company. The old 0317 scout snipers were infantry Marines who went to sniper school; 0322s are recon Marines who add sniping to their already deep skill set. The standard is higher, the pipeline is longer, and the expectations are enormous. But you're operating at a level very few Marines ever reach.
The Real Life
Same dimensions, side by side. 0306 on the left, 0322 on the right.
Advising commanders on weapons employment, running ranges, managing arms rooms, overseeing marksmanship programs, and serving as the resident expert on everything from M4s to TOW missiles. You are the battalion or regiment's weapons guru and maintenance authority. Administrative duties include armory management and accountability.

Warrant Officer Basic Course at Quantico, followed by specialized weapons training. The pathway to WO in the infantry community requires extensive enlisted experience — most 0306s were senior SNCOs before selection. The WO culture is distinct: you are a technical expert, not a commander.

High. You are expected to maintain infantry-level fitness while serving as the technical expert on all infantry weapons systems. Field time is substantial.
—
The 0306 Infantry Weapons Officer is one of the most respected warrant officer billets in the Marine Corps. You are the subject matter expert that battalion commanders rely on for everything weapons-related. The path to get here is long — years of enlisted infantry experience — but the payoff is a stable career doing what you love without the command burden of commissioned officers. The recruiter doesn't recruit for this MOS; it finds you. Civilian translation is strong in the firearms industry, defense contracting, and law enforcement training. The downside: warrant officer promotions are slow, and the billet structure limits where you can be assigned.
