11B vs 74D
Infantryman (USA) vs Chemical, Biological, Radiological, and Nuclear (CBRN) Specialist (USA)
Two soldiers walk into a motor pool. One works there. The other just needs their vehicle back. Both are trapped for the next 4 hours.
Drop a camera into the 11B's day and you'd see: the civilian translation of your resume is 'I can sleep standing up, carry things that weigh more than my future, and I have extremely strong opinions about which MRE is the best. Pan over to the 74D and the footage looks like a different documentary entirely: you'll train entire units on CBRN defense and watch them forget everything inside of 90 days, then train them again. Same flag, same anthem, same inexplicable attachment to a career that doesn't always love them back.

Recruiter vs. Reality
The pitch versus what people who actually did the job report back.
“As an Infantryman, you'll be the backbone of the Army. You'll lead soldiers in ground combat operations, master weapons systems, and develop unmatched leadership skills that translate directly to civilian careers in law enforcement, security management, and executive leadership.”
You will spend approximately 4,000% more time cleaning weapons than firing them. Your 'leadership development' is standing in formation waiting for someone to get yelled at for something you also did but didn't get caught doing. 'Master weapons systems' means you'll carry an M4 that was manufactured when Britney Spears was still relevant and learn to field strip it in your sleep — which is good, because you won't be getting much of it. The civilian translation of your resume is 'I can sleep standing up, carry things that weigh more than my future, and I have extremely strong opinions about which MRE is the best.' Your knees will file their own VA claim. You'll hate every second of it and talk about it for the rest of your life like it was the best thing that ever happened to you. Because it was.
“You'll be the Army's expert on the threats most people don't want to think about — chemical agents, biological hazards, radiological contamination, and nuclear threats. Every installation, every brigade needs a CBRN NCO. You'll train the entire unit on protective equipment and decontamination procedures, run gas chamber qualifications, and be the person everyone turns to when the CBRN alarm goes off. HAZMAT certifications, emergency management credentials, and the FEMA pipeline are legitimate civilian paths. Homeland security and emergency response agencies specifically recruit CBRN-trained veterans.”
You run the gas chamber. Not metaphorically — you are the person who cracks the CS canisters, watches grown adults rediscover the concept of tears, and evaluates whether their mask sealed correctly while their face melts off. Every soldier on post hates you for three days before a gas chamber qual, and silently respects you after, because you were in there with them. You are the CBRN NCO: mask confidence tests, MOPP level drills, detector calibrations that are due yesterday, JSLIST suits that were stuffed back in their bags wrong by someone who will claim they weren't, and M8A1 alarms that go off whenever a vehicle drives past. Your detection equipment — JCAD, CAM, M256 kit — is the most important gear nobody funds. You'll train entire units on CBRN defense and watch them forget everything inside of 90 days, then train them again. The decon site you build and tear down will never process an actual contamination casualty. That is a good thing. Your HAZMAT certifications are real, your emergency management pipeline is real, and your ability to explain nerve agent mechanisms at a dinner table is a skill that plays differently depending on the crowd. Nobody thinks about CBRN until they need it. You make sure they're not surprised when they do.
The Real Life
Same dimensions, side by side. 11B on the left, 74D on the right.
PT at 0630, formation, weapons maintenance, ranges, and tactical drills. Most days end by 1700 but field problems run 72+ hours. Garrison time is heavy on maintenance and cleaning — you will mop floors that are already clean.
CBRN defense training, detection equipment maintenance, decontamination operations, and NBC reconnaissance. You train the unit on CBRN defense procedures, maintain detection equipment, and serve as the commander's advisor on chemical, biological, radiological, and nuclear threats. Garrison includes a lot of training management and equipment maintenance.
OSUT at Fort Moore (GA) is 22 weeks of combined Basic and Infantry training. High-intensity, high-washout environment. Land navigation, live fire exercises, and forced marches. The last few weeks are the best — squad live fires and a final field exercise.
AIT at Fort Leonard Wood (MO) is about 11 weeks. Covers CBRN defense fundamentals, detection equipment, decontamination procedures, and reconnaissance. Training includes working in live agent environments at the CBRN training facility, which is an intense and memorable experience.
Extremely high. Rucking 35-70 lbs over rough terrain, room clearing, casualty drags, and operating on minimal sleep. Your knees, back, and shoulders will take a beating.
Moderate to high. Operating in full MOPP gear (CBRN protective equipment) is physically demanding and hot. Decontamination operations involve heavy labor. The gear adds significant physical burden to any task.
The recruiter will tell you infantry is the backbone of the Army, and that part is true. What they won't tell you is that peacetime infantry is 80% maintenance and cleaning, promotion is glacially slow because everyone has the same MOS, and your body will age faster than your peers in other fields. The camaraderie is unmatched — you will form bonds that last a lifetime — but the day-to-day can be mind-numbing between field rotations. If you want to be an infantryman, go all-in on schools and tabs, because that's what separates the ones who love it from the ones who count down their contract.
CBRN specialist is the Army's "break glass in case of emergency" MOS. The recruiter will describe defending against weapons of mass destruction, and that is the doctrinal mission. What they won't tell you: in garrison, nobody takes CBRN training seriously until they have to. You will spend a lot of time trying to get units to prioritize CBRN defense training when they would rather be at the range or doing maneuver exercises. The gas chamber is the most memorable thing most soldiers know about CBRN, and you are the person who runs it — which makes you simultaneously feared and avoided. The civilian translation is stronger than you might expect: HAZMAT response, environmental safety, nuclear plant safety, and emergency management all value CBRN experience. The Department of Energy and FEMA both recruit from the 74D community. Promotion is slow because the MOS is small, but specialization opportunities exist.
