What are the 10 most important MOSs in the Army?

I would say All Combat Arms are the bread and butter of the Army.

With that said, these 10 support fields are key....
Quartermaster (Supply)
Quartermaster (Cooks)
Signal
Medical
Ordnance (Ammo)
Ordnance (Maintenance)
Ordnance (EOD)
Finance
Transportation
Cyber (in this day and age with computerized gear yeah hackers and counter-hackers do count)

Infantry, Armor, Engineering, Logistics, ADA, Intelligence, SF, FA, Aviation, EOD

combat arm

I am ashamed to admit this,but our old friends the zoomies as we used to call them back in the day, yes the US Airforce had a mission statement as follows"The mission is an eighteen year old with a rifle every thing else is support"I know SGT this in no way gives you a list of ten most important MOSs in the Army,I just found it mind boggling the Air Force knew what a rifle was!

Little biased, 91B

1. Doctor 2. Medic 3. EOD 4. Cook 5. Artillery 6. Infantry 7. Supply 8. Any aviation MOS 9. Finance 10. Any mechanic MOS

All combat arms, all logistics (supply and maintenance, medics, common and finance!!
11 series, 19 series, 13 series, 15 series, 92 & 91 series, 68 series, 25 series and finance and last but not least...the Padre's. Gotta have Holy Joe with ya and stay in the good graces!!

Can't move if you don't have fuel...

As a soon to be ROTC nursing student and former 88M I see no MOS as less important. Each MOS is a functioning cog of a well oiled machine.

All of them are important, need them all to ad the other to accomplish the mission!
