Ok so what's your definition of Locked and Loaded?

Being retired AF, they definition was always explained as, "Lock the bolt forward on an empty champer; Load a full magazine under it."  Reason was so there were no ready to go weapons until the "order" came to charge the weapons.  That was even in a hostile enviroment...

One in the chamer, full load under it and weapon on safe.

Copied this from Saving Private Ryan Online:

The origin of the phrase "lock and load" is not entirely clear, as there are two similar, yet distinct, explantions for its origin. Regardless of its exact origin, the phrase has come to relate to any activity in which preparations have to be made for an immediate action.

One explanation of the phrase comes from the actions needed to prepare a flint lock rifle for firing. In order to safely load a rifle of this type it was necessary to position the firing mechanism in a locked position, after which the gun powder and ball could be safely loaded into the rifle barrel without any chance of the rifle misfiring.

The second explanation is that the phrase (as "load and lock") originated during World War II to describe the preparations required to fire an M1 Garand rifle. After an ammunition clip was loaded into the rifle the bolt was pushed forward in order to "lock" a round into the chamber.

Quite simply, it means to Lock a loaded magazine into the weapon and Load the weapon by charging the breech chamber with a live round. It is a military command given usually at the firing range. It was also intended to be used to prepare for imminent combat, but I doubt if any troops had to be told.

You know it's funny, the AF always carries the M-16 with an empty chamber on base, but the M-9 has a round in the chamber, hammer down and safety off....
