G1, G2, G3 etc etc etc

Can anyone give me a simple list of what each one covers?

I think:
G2 is personnel
G3 is training and operations
G4 is equipment / stores

But what about G1 and all the rest? I think it goes up to G9??

And anyone know what the G stands for?!

I've put the nomenclature and some descriptors as used by PJHQ in here for completeness sake. Clearly not all HQs will use all of them. An Army HQ uses 'G' in place of 'J' hence 'Operations' in a Bde HQ is 'G3', not 'J3', although this is operation dependent.

Please feel free to ask questions.

1. The J7 staff would normally be part of a peacetime headquarters organization; the Cell is unlikely to be included in an operational headquarters.

2. The Resource and Finance staff may form a special group, separate from the main headquarters.

3. A Civil-Military Coordination Centre (CIMIC Centre) may be formed, under the direction of the Chief of Staff (COS) in order to effect coordination between the allied joint force and international bodies, non-governmental or private voluntary organizations.

4. The Joint Force Commander may have a Staff Judge Advocate on their personal staff.

5. A Press and Information Centre (PIC) may be established. The Head of the PIC would be responsible to the COS.

6. 'G' stands for 'General' as in 'General Staff'. 'J' is 'Joint', 'A' is 'Air', and 'N' is 'Naval' for the matelots!
It originates from the term General Staff Officer, the abbreviation used to be GSO etc

G1 Personnel
G2 Security
G3 operations, Training & Plans

And of course the Naval version is N - so N8 is Finance / CivSec.
