Here is where I'll make a feeble attempt to define the terms some of you may be unfamiliar with. I've forgotten most of the definitions, so if any of you see any glaring mistakes, please let me know.

ARVN

Army of the Republic of Viet-Nam

Avionics

Aviation Electronics - The field I worked in while in the Marines.

BLT

A Battalion Landing Team, is a battalion of Marines on board a ship to be available for any trouble spot that may occur around the world.

Boondocks

When you are out in the field in the middle of nowhere, you are in the "boondocks."

Boondockers

Boots. More specifically, the ankle high boots, that used to be issued to Marines.

Bulkhead

Wall.

Bunker

The "bunkers" I refer to, are defensive structures we built (normally out of sandbags and steel matting), to offer protection during rocket and mortar attacks.

Casings

These are the empty brass (Usually) shells extracted from a weapon, after it's been fired. (As used in JOHN 3:16.)

Cover

A hat.

Chopper

A helicopter.

Debark

To exit, or to leave. e.g. to debark a plane or a ship.

Deck

D.I.

I'm sweating blood, just thinking about him. LOL This is the gentleman who transforms snot-nosed kids, just off the street, into the most elite fighting men in the world...U.S. Marines!! (Excuse my prejudice, and terminology!) He is the USMC Drill Instructor. GySgt.Osgood..... where ever you may be, I salute you and thank you from the bottom of my heart. Every Marine alive today owes a debt of gratitude to these gentlemen.

Embark

Opposite of "debark."

Extraction

This was when the helicopters went in to remove the infantry from the field. If the infantry was in a soup sandwich, it was called an "emergency extraction."

Field scarf

A necktie.

Fire Team

The smallest unit in the Marine Corps infantry organiztion, consisting of four Marines. After that, the magic number is three. Three fire teams make up a squad, three squads a platoon, three platoons a company, three companies a battalion, three battalions a regiment, three regiments a division, three divisions a corps, and beyond that you get into armies. That was my feeble attempt to explain Marine Corps infantry organization. Bear in mind there are understrength units and re-inforced units. For instance a unit may have a sniper unit, mortar unit, machine-gun unit, tanks, artillery, etc. assigned. The organizations I described are the basic ones, and if I'm in error, one of you grunts can feel free to correct me. I'm trying to remember 40 years ago. :-)) By the way, when you ask a Marine what outfit he was with, he is liable to say 1/3, which would be short for 1st battalion, 3rd regiment, if my memory serves me correctly.

Galley

A kitchen.

Gunny

Short for gunnery sargeant. (GySgt.) An enlisted rank in the Marine Corps.

Gung Ho

H&MS

Headquarters & Maintenance Squadron - I've been told they no longer exist. They were the Marines who repaired the components of the aircraft. Each MAG had a H&MS. e.g. MAG-16 had H&MS-16. H&MS also took care of the majority of the administration work of the MAG. It functioned like this, a Marine from an operational squadron (HMM-162) would pull a radio from a UH-34, and send it to H&MS for repair. H&MS would then issue a repaired radio to replace the bad one.

Leatherneck

A term used to describe U.S.Marines. It was derived from the leather collars, worn on the jackets of Marines back in colonial days. Marines served as part of ship's companies, and the leather collar protected their necks from sword slashes during combat. sheez...I hope I'm right. :-)

MEDEVAC

MEDical EVACuation. When a Marine was wounded or killed in action, a Medevac helicopter was called to evacuate them.

Mess

Mess hall

Where you ate your meals, when on base. In all truthfulness, most Marine mess halls served pretty good chow (food).

MOS

Military Occupational Specialty. A four numeral code that identifies your job. All infantrymen (Grunts: written with the highest respect) carried an 0300 MOS and all Marines are basic infantrymen. I was avionics with a 6212 designation. 6200 being avionics and the 12 designating a specialty within the field.

They were thoroughly defeated on all fronts, but the media played it up as a major catastrophe for the U.S. and it became the beginning of the end of our involvement in the Vietnamese war. Don't even get me started.
