Decapitation – Achieving strategic paralysis by targeting political leadership, command and control, strategic weapons, and critical economic nodes; Deception – A strategy that seeks to deceive, trick, or fool the enemy and create a false perception in a way that can be leveraged for a military advantage
Military strategy is a set of ideas implemented by military organizations to pursue desired strategic goals. [1] Derived from the Greek word strategos, the term strategy, when first used during the 18th century, [2] was seen in its narrow sense as the "art of the general", [3] or "the art of arrangement" of troops.
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air, is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
Strategic planning's role is "to realise and to support strategies developed through the strategic thinking process and to integrate these back into the business". [14] Henry Mintzberg wrote in 1994 that strategic thinking is more about synthesis (i.e., "connecting the dots") than analysis (i.e., "finding the dots"). It is about "capturing what ...
The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first approached the speed of sound, these effects were seen as constituting a barrier, making faster speeds very difficult or impossible.

There are many kinds of transduction process that convert energy from some other form into sonic energy, producing a sound wave. There is one fundamental equation that describes sound wave propagation, the acoustic wave equation, but the phenomena that emerge from it are varied and often complex. The wave carries energy throughout the ...
