I think a satchel is like a soft brief case.

Definition: a bag carried on the shoulder by a long strap and typically closed by a flap.

Saw the video of him carrying it in. Wasn’t stuffed to the gill, but you could see it had something in it.

"A satchel charge is a demolition device, primarily intended for combat, whose primary components are a charge of dynamite or a more potent explosive such as C-4 plastic explosive, a carrying device functionally similar to a satchel or messenger bag, and a triggering mechanism; the term covers both improvised and formally designed devices. "

True. But I was only in it for the [lame] humor [and possible misspelling of "scintilla"]
