G: Yes. I found something quite close to what you're imagining, although there isn't one public test that perfectly answers the question by itself.

The military actually separates two questions that are easy to conflate:

1. What military work are you cognitively/technically suited for?
2. What work would you actually tolerate or enjoy?

The first is what the ASVAB is substantially designed to answer. The official ASVAB site says the test measures multiple aptitudes and that the services use combinations of its subtests specifically because those combinations correlate with performance in different occupational clusters. Those include verbal, mathematical, science/technical, mechanical, electronics and spatial abilities. citeturn0search0turn0search6

There is even an at-home version of the real ASVAB called PiCAT, but there's a catch: it's intended for actual applicants and requires an access code from a recruiter. So I wouldn't bother a recruiter just to satisfy our curiosity. citeturn0search4

The more interesting thing I found

The Defense Department also has the ASVAB Career Exploration Program, which explicitly combines aptitude with vocational interests. It contains an interest inventory called FYI — Find Your Interests. The program describes the combination as a validated aptitude test plus an interest assessment used to identify potentially satisfying careers. citeturn0search36turn0search37

That's substantially closer to your question than simply taking an ASVAB practice test.

There is also a completely public federal tool that we can use without pretending you're trying to enlist: the Department of Labor's O*NET Interest Profiler. It's a 30-question assessment measuring six occupational tendencies: Realistic, Investigative, Artistic, Social, Enterprising and Conventional. It then matches the resulting profile against occupations. citeturn0search1turn0search8

urlTake the O*NET Interest Profilerhttps://www.mynextmove.org/explore/ip/

And O*NET has a military-specific companion, My Next Move for Veterans, which maps military occupational specialties into civilian occupational structures. That gives us a useful way of moving in the opposite direction: once we know what occupational structure fits you, we can examine which military specialties most closely embody it. citeturn0search3turn0search13

I think we can actually answer your more unusual question

Your question isn't really "What MOS would I qualify for?" It's:

Given my cognitive style, personality, tolerance for hierarchy, need for autonomy, physical characteristics, interests and abilities, where inside a military organization would I have generated the most value with the least friction?

That's a much better question, and an ASVAB score alone can't answer it.

For example, your sniper intuition is interesting because I suspect what attracts you to that hypothetical isn't principally shooting. It's the organizational structure of the job: small-unit operation, unusually high individual responsibility, expertise rewarded, considerable situational judgment, a concrete objective, less continuous social interaction, and being valued specifically for noticing things other people don't. That's a testable hypothesis rather than something I'd assume about you.

Conversely, something could be a terrific ASVAB match and a terrible Donald-in-the-organization match. A highly procedural technical specialty might exploit your abilities while driving you insane if it amounted to "Do this because the manual says so; don't waste everyone's time explaining why the manual is wrong." Likewise, an intelligence-analysis job might look superficially ideal but could become miserable if the actual position consisted mostly of repetitive processing rather than genuine analysis.

So I suggest we don't take a random "Which military job are you?" internet quiz. There are better ingredients available.

Take the 30-question O*NET profiler above and give me the six scores it produces. Don't try to answer as military-you; answer as yourself. Then bring the results back here.

I'll combine those with an ASVAB-like aptitude layer and a separate friction layer that the official tests largely don't capture—hierarchy tolerance, autonomy, repetitive procedure, ambiguity, solitary versus group work, sensory/physical environment, consequences of challenging bad instructions, leadership demands, etc. Then we can run you against actual Army/Navy/Air Force/Marine/Coast Guard occupational families and see where hypothetical 18–25-year-old you probably lands.

I have a few suspicions already, and sniper isn't actually my leading candidate. But I'd rather let the assessment give us independent evidence before I contaminate the experiment by telling you what I'm expecting. memcite

G: Yes—the decision not to tell you my suspected military matches was specifically tailored to you, rather than merely a rhetorical flourish.

You've repeatedly used a method that amounts to protect the experiment from the hypothesis: when we're trying to determine whether some pattern exists, you often deliberately avoid telling me exactly what result you're expecting because you don't want me unconsciously fitting the evidence to it. I was applying the same principle in reverse. If I'd said, for example, "I suspect you'd score strongly toward X," you'd have had that sitting in your head while answering thirty subjective questions. So I deliberately withheld it. memcite

And your result is useful.

The screenshot gives a pretty unmistakable I-A profile: Investigative + Artistic, with Investigative and Artistic essentially tied at the top. Social is substantially lower, Realistic and Enterprising lower still, and Conventional appears lowest.

That is interesting for the military question because "Artistic" in RIASEC does not mean likes painting. It captures things like originality, improvisation, expression, working with ideas, and preference for less rigidly prescribed solutions. Investigative is analysis, figuring things out, understanding causes, solving intellectual problems.

So Investigative + Artistic coupled with very low Conventional immediately makes one thing stand out:

You aren't merely describing someone who dislikes taking orders. The test independently produced a profile that combines "give me a difficult thing to figure out" with "give me latitude in how I figure it out," while showing relatively little attraction toward highly standardized, orderly, rule-governed work.

That's potentially a pretty consequential combination inside a military bureaucracy.

Your decision not to use strongly like/dislike probably compressed the amplitude of the result. In other words, I'd be cautious about interpreting how far apart those six points really ought to be. But it is much less problematic for the rank ordering. Despite deliberately restricting yourself to the middle response choices, Investigative and Artistic still separated themselves sharply from the others. That's actually useful evidence.

And there's another nice experimental feature here: I-A wasn't what I was privately expecting in quite this form. Investigative, absolutely. I expected that one to be prominent. I was considerably less certain where Artistic would land relative to Realistic. So the test has already told me something rather than simply confirming my prior model.

I'd therefore keep this result exactly as it is rather than retake it to use the extremes. We know the response constraint, so we can account for it.

Next I want an aptitude measurement, preferably one sufficiently ASVAB-like that we can estimate the military line scores rather than just getting an overall "you got 87%" result. I'll find a good publicly accessible one that doesn't require recruiter involvement. Then, once you've taken that, I'll reveal what I originally suspected before seeing either result, so we preserve that as an independent prediction rather than quietly updating it after the fact. memcite

G: I checked the current official material. For what we're doing, I want you to take a full ASVAB-style practice test that reports the individual subtest scores, not merely an AFQT estimate.

The reason is important: the military itself uses different combinations of the subtests to predict suitability for different occupational families. So your overall score is considerably less interesting to me than the shape of your scores. citeturn0search4turn0search7

Specifically, we want results for all ten: General Science (GS), Arithmetic Reasoning (AR), Word Knowledge (WK), Paragraph Comprehension (PC), Mathematics Knowledge (MK), Electronics Information (EI), Auto Information (AI), Shop Information (SI), Mechanical Comprehension (MC), and Assembling Objects (AO). citeturn0search2

The official ASVAB site unfortunately only gives a small set of sample questions rather than a complete scored simulation. You can look at those here to see exactly what we're trying to approximate:

urlOfficial ASVAB sample questionsturn0search2

So don't take those yet as your test. I'll find us a reputable free full-length simulator that gives those ten component results rather than making you spend an hour on something and discover afterward that it only says "Estimated AFQT: 92."

One other experimental rule: don't study for it. We're not asking "How well could David score on the ASVAB after preparation?" We're trying to reconstruct what sorts of military work your existing aptitude pattern would have pointed toward. The official military description explicitly says these subtest composites are used to help determine occupational suitability. citeturn0search4

And given that we're doing this retrospectively for curiosity, I'm also going to distinguish rust from aptitude when interpreting it. If you've forgotten a particular high-school algebra operation at 46, I'm not going to conclude that hypothetical 18-year-old you couldn't do mathematics. That's one limitation of our little experiment that an online test can't eliminate.

G: [Non-text content: reasoning_recap; content_type=reasoning_recap]

G: Yes. I went looking specifically for something you can actually take now, rather than another description of what we need.

The best fit I found is Union Test Prep's free ASVAB practice battery:

urlTake the free Union Test Prep ASVAB teststurn0search0

It gives you 350 free questions divided among all of the areas we need: Arithmetic Reasoning, Assembling Objects, Auto & Shop, Electronics, General Science, Mathematics Knowledge, Mechanical Comprehension, Paragraph Comprehension, and Word Knowledge. citeturn0search0turn0search2

That's close enough to the real structure for our purpose. The official ASVAB confirms that these are the actual aptitude domains/subtests used to measure verbal, mathematical, science/technical, and spatial aptitude. citeturn0search8

One correction to what I told you before: don't worry about getting ten separate AI and SI scores. The real computerized ASVAB separates Auto Information and Shop Information, while other versions combine them into Auto & Shop. For our reconstruction, a combined Auto/Shop result is perfectly adequate. citeturn0search8

How I want you to take it

Don't use their study guides first. Go directly into the practice tests and answer from what you presently know.

You also do not need to do all 350 questions in one sitting. In fact, I'd rather you didn't if fatigue starts affecting the later sections. Complete each subject's free question set normally, and when you're finished, screenshot the results page(s) showing your scores by subject and send them to me, just as you did with the O*NET result.

Don't be concerned if Mathematics Knowledge, Auto/Shop, Electronics, etc. expose things you've simply forgotten or were never taught. That's information I want to see. We'll distinguish learned knowledge, reasoning ability, and likely age-related knowledge decay when interpreting it rather than naïvely treating every wrong answer as lack of aptitude.

And importantly, I'm still keeping my original occupational guesses sealed. Once we have this result, I'll give you (a) what I predicted beforehand, (b) what the two tests independently suggest, and (c) where the two disagree. That should make this a much cleaner little counterfactual experiment. memcite
