Multiple Application is somewhat generic in that it only refers to the use of multiple weapons - it purposely does not specify whether they must be simultaneous, in sequence, or for the same intention; although it is highly implied that the weapons should be simultaneous or very close in timing.

Most commonly, Multiple Application refers to two (2) or more weapons used simultaneously.or almost simultaneously.

Multiple Application differs from sophisticated in that Multiple Application is two (2) or more (Elementary) maneuvers executed simultaneously and sophisticated is a single maneuver with two (2) or more effects.
