scope:

The information in this publication does not supersede any legal requirements (domestic US law for operations in the US and for operations outside the US: US law with extraterritorial application, applicable international agreement requirement, or combatant command directive) that specify how things must be done. For the purpose of this document, "expedient" is defined as "a means devised or employed in a time and place where prompt action is essential." Expedient engineering does not preclude using normal engineer practices where time and materials are available.
