Gun truck : an armored and heavily armed vehicle used for convoy security. Usually any truck with any type of "crew served" weapon was called Gun Truck... even if it had a "Hajji" machine gun.
GWOT : global war on terrorism. They came up with another medal...you were supposed to have actully been deployed over seas to get this, but I know of one National Guard REMF who never left California who somehow ended up with one.
Haji : 1: Arabic word for someone who has made the pilgrimage to Mecca; 2: used by the American military for an Iraqi, anyone of arab decent, or even of a brownish skin tone, be they afghanis, or even bangladeshis; 3: the word many soldiers use derogatorily for the enemy.
Haji armor : improvised armor, installed by troops hiring Iraqis to update the vehicles by welding any available metal to the sides of Humvees
Haji mart : any small store operated by Iraqis to sell small items to Americans.
Haji patrol : 1: escort detail; 2: Local National unit is also referred to as the Haji patrol, with all the projects that are being performed by the local nationals.
Haji shop : even the smallest base has some form of what soldiers call a "haji shop" or, in more politically correct terms, a shop run by locals. Frequently near the PX, the "Haji" shop would sell everything from cigarettes to knockoff sunglasses to pirated DVDs.
Hillbilly armor : Improvised vehicle armor. Most often appeared to have been made in a high school welding shop class. Typically a half-inch of scrap steel hastily cut in the shape of the door and welded or riveted on. SecDef Rumsfeld in December 2004 lied about the need for such scrounging. That lying bastard claimed that there was plenty of armored vehicles in Iraq...I still saw a lot of Hajji Armor in Nov 2005 before we left. How could he say that with a straight face...
(updated...I had to search for the above pic of the USMC Humvee. They put 1/2 metal plates on the side and hung Kevelar blankets over that. It would stop small arms rounds.-- From Al Qaim Iraq, July 2005)
