Air Force “unit” Designations Of The United States
The US Army Air Forces, in addition to its combat units and flying units, also had non-flying units and organizations which used several types of designations during the period of the AAF (June, 1941 into September, 1947). In addition, the AAF restructured its domestic and continental structure during early spring 1944, this resulted in a base unit structure. The base units centralized the command of the support functions at a location and created a communication and organizational relations among flying and non-flying elements. It established a logistics basis for air operations. This restructuring resulted from a February 1944 Army Air Forces Headquarters order that units at each installation to be consolidated into Army Air Forces base units. The base unit structure in turn was replaced by base Wing structure in which commanders controlled both facilities and organizations. This arrangement soon lead to the Wing structure used today by the USAF that eliminated the Group level. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...
