Had a few minutes reprieve so I thought I'd say "I knew That".
You forgot the most important guy in the Company the 1st Sgt..
We got a new Co. that was a "Ring Knocker" and he used to go
bananas with some of the Butter Bars etc in the BN.
What he did one day was to form up the Bn. and DISMISS all
Commissioned officers for 36 hours after he told them that in his
opinion he could run the Bn. With the NCOS and WITHOUT the
Officers and he did exactly that. When the 36 hours was up he
reminded the Commissioned Officers that they were ONLY PART
on the Bn.
Necessary but not needed.
There were a lot of long faces and bruised egos but he proved his point

Whilst browsing I found this and wondered what you meant by "S" designations. I saw what you meant once I opened the topic.
I was, of course, hurt by the fact that you don't have S-6 represented. Just remember, the three pillars of a functioning unit are to shoot, move, and communicate! Can't do much of the first two without the third!! ![]()
Something else one might hear is "G" sections. These are for Division sized units and up (commanded by a general [thus "G"]). I work in the G-6 (communications) section for II MEF.
Something that is a little more recent in nature (I believe) is the "J" designator. They correspond to the meanings of the S and G sections, but are the designations for joint commands (composed of individuals from multiple service branches.)

CaptO where does a PFC fit in
Well Rock, being a private first class is much better than being a private no class (E-1 or 2). At least there was a vote passed in congress to get you your PFC rocker!
In the Marines a PFC is an E-2. An E-3 is called a Lance Corporal (inherited from the British Royal Marines.) A PFC has one stripe and a Lance Corporal has one stripe above two crossed rifles. Getting you crossed rifles is a big deal because it shows you’re not the bootest of the boot. I'm sure you were probably interested mostly in the pay hike, yes? The mud was probably just as cold and wet in Italy as a PFC as it was a Private. Mauser bullets probably don't care much about the difference between E-2's and 3's as well.

I'd say PFC or no, you made an impression on people!

Ah,
the only reason that was left out, because it didn't exist in the army records from NARA from WWII. Records were provided for S-1, S-2, S-3, and S-4.
Sorry there soldier!

Drat it all!
I started looking up S/G-6 to see if I could find out when it began and had no luck so far. I did find that on the Wikipedia entry on staff positions that G stood for "ground" vice "general" as it was a designation for Army and Marine. It also said that was NATO so I don't know.
Oh, well. Perhaps I can try to look back in books and records and find out when the term was first coined.

Marion,
The G-1/S-1 designation referred to the Personnel Officer during WWII, to my knowledge there were no adjutants below division level.
Higher headquarters starting at the Army level used, for example, G-5 (Civil Affairs/Military Government) and additional designations as the need arose.
Hope this helps clarify matters a little.
Jim
Hi Jim:
Ah, they did have adjutants at the battalion/regimental level. To my knowledge, G designations begin at divisional level and S designations were below. ![]()
