[Milsurplus] Army Departmental Abbreviations

[Richard Arland, W3OSS]

OK, I'm a feathermerchant. I'll admit it!

Not being Regular Army, I am wondering about the various abbreviations for
Intelligence, Communications, Logistics, Operations, etc.

G-2 I believe is Intelligence.

J-6 was Commo when I was working with SOTFE back in the early '80s.

Is G-6 the same thing but used for just Army units not something like SOTFE
which was a joint command (hence the "J").

OR....am I all wrong in my thinking?

Help would be appreciated.
