I'm finally a Major

[Ithoriel]

I have one question WTF does the second part of this mean "Major Fielder recently returned from Baghdad, Iraq, where he was the
LNO to a Maritime Component, representing a NAVCENT Bahrain based UK Naval One Star to the U.S. Forces-Iraq in the J3 lane of the Joint Operations Center. "

LNO - he was a Liaison Officer ... or he's the Latvian National Orchestra .... take your pick.

NAVCENT - United States Naval Forces Central Command

UK Naval One Star - A Royal Navy Commodore

J3 - Current Operations

Because, of course, we are oh sooo familiar with those terms!!

Isn't everyone?

Wrong! Wrong! Wrong!

LNO - Leicester Naturism Office
NAVCENT - Naturist and Vegan Centre
UK Naval One Star - Type of Belly Button
J3 Lane - a place where naturist vegans congregate for Joss, Jiggling and Juices

[Leman]

I'm sure we've only just gone down this route - oh, hang on. That was anagrams.

LNO - London natives objectionable
NAVCENT - currency used by fleets in the Eurozone
UK Naval One Star - next to lowest rank in the galley
J3 Lane - Postal shorthand for Jasmine, Juniper and Jojoba Lanes in East Kilbride, which meet at a triple junction near the football ground.

I had guessed most of that

The bits that I found particularly confusing were the N in LNO and the lane 

Interesting that the USN doesn't appear to have the rank of Commodore, instead splitting Read Admirals into two halves

Splitting the rear into two halves was strangely evocative! 
Incidently I think we do still use Commodore as the curtesy title for the senior captain present, but could be wrong.

good one Leman!

[Dave Fielder]

LNO ... Last National Objector
One Star ... I didn't do very well in McDonalds customer service
J3 ... Just Jumped Jauntily

Congratulations Dave.
