What are the 10 most important MOSs in the Army?

Could've predicted that you would get a whole lot of "Army only runs smooth with all MOS's". Doubt that was what you were looking for, but it was inevitable on RP haha

I've changed my list as follows. Consider the situation to be that we are facing WWIII with a world super power like our own.

1.Recruiter- we are a all volunteer Army. I'd like to keep it that way. Knowing some civilians I've met could be forced to have my back in combat doesn't give me piece of mind so say what you will.
2.Supply- we need stuff!
3.Food service operator- this officer will order food on a large scale. We can figure out how to cook it if we need to buy we need this guy if we are going to outlast the enemy.
4.Ammunition-obviously
5.Infantry-arguably one of the most important on here aside from the support jobs that enable them to do what they do.
6.Commo- if we can't communicate we are doomed.
7.Medic- to keep us alive and keep up retention.
8.Field artillery-the enemy may have this. Where would we be without it?
9.Mechanic- to enable the infantry to take the fight to the enemy.
10.Human Intelligence- other Intels are important but this is what you get on the ground from the people themselves. How would we know how many soldiers we need to recruit to defeat the enemy. Also look at our strategic attack on D-Day. We had to collect that info. Some may have been signal though. But these collectors can't get anywhere without the Infantry taking them there.

I'll tell you the least important, prisoner.

If it is self sufficient every mos is needed, what not needed is those that think they better then the team

So I know the most popular answer is going to be "We all work together" and "No MOS is more important than another" and yadda yadda. But I'll try to answer the OPs question in the spirit that yes, we are all one Army, but that isn't the answer he is looking for.

I'd start with the basics, Combat Arms.

11B - Infantry. The backbone of the Army. I could see the argument where people might say 11Bs are less important because anyone in the Army should be able to function as a riflemen, but the sad truth is in this day and age that just isn't true. 11B's have a very simple existence in the Army (save for those on special duty like honor guard) they are either fighting, or training to fight.

13B - Cannon Crewmember. King of the Battle. I considered putting them ahead of Infantry but in the end I decided not to just because it seems more and more often ROE limit their use. Still, I'd call them a very close 2nd to infantry. Once upon a time if you had some Infantry and you had some Artillery you called that an Army.

19K - M1 Armor Crewmen. Tanks. Nuff said.

12B- Combat Engineer. When you need it blown up, accept no substitute.

68W - Healthcare specialist. Aka Combat Medic. Because some times the whole in you is too big for a field dressing.

Ok so there are your 4 main fighters and the hole plugger. Now we could back fill in other combat support jobs like cav scouts or foreword observers but I think you can't really mention the top 10 'most important' MOSs without half of them being soft support.

92Y - Unit Supply Specialist. Army needs gear.

91B - Wheeled Vehicle Mechanic. Gear needs to work, slap different letters on there for different systems, sorry Mechanics I'm grouping you together,

15 - Aviation Officer. Helicopter are really useful. Arguably not a 'soft support' since no one would call and AH-64 soft.

35F - Intelligence Analyst. Knowledge is power.

56A/M - Chaplin / Chaplin Assistant. Because 80-90% of us believe in God in some way, shape, or form.

All Army is trained in 11B at Basic Training. Personally I feel they are all needed or they wouldn't have them. The "foot soldiers" may do MOST of the fighting but the Finance, Administrative, Medics, Cooks, and the others that are lovingly called "House Cats" are just as important as the fighting men. We ALL are trained the same way in Basic Training and can hold our own in battle. I know, I've done it.

1. Cooks
2. Admin
3. Supply
4. Communication
5. Logistics
6. Motorpool/maintenance
7. MPs
8. 18X
9. Chaplain
10. Medics

For bonus, not an MOS but it's very important, a fucking 1SG.

Because mission demands will determine which MOSs are most important at any given time, I won't list any here. What I REALLY like to see is the Army stop being so dependant on contractors. Especially in what used to be called Combat Support and Combat Service Support. Both Russia and China are ratcheting things up and if we find ourselves getting into a conventional war with either of them, those contractors will be long gone or billing Uncle Sam millions to flip a hamburger in a field kitchen or drive a truck. I'm a bit off subject, I know, but I felt it needed to be said.

All Jobs in the military are equally important. Not one is as important as the other no mater what branch you are in.

Wait wait wait...I thought combat mop, buffer and waxer.
