The atmosphere of Earth is the layer of gases, known collectively as air, retained by Gravity of Earth, Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating Atmospheric pressure, pressure allowing for Water#Liquid water, liquid water to exist on the Earth's Planetary surface, surface, absorbing ultraviolet Solar irradiance, solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between Daytime, day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% Carbon dioxide in Earth's atmosphere, carbon dioxide, and small amounts of other gases.

The CAC also operated heavy and railway artillery during World War I. History As early as 1882 the need for heavy fixed artillery for seacoast defense was noted in Chester A. Arthur's Second Annual Message to Congress where he noted: In 1885 the Endicott Board was convened under the subsequent Grover Cleveland administration, chaired by Secretary of War William Crowninshield Endicott. This board recommended a large-scale program of harbor defenses at 29 ports, including guns, mortars, and mine fields. Most of their recommendations were implemented and new defenses were constructed by the United States Army Corps of Engineers 1895–1905. As the defenses were constructed, each harbor or river's installations were controlled by Artillery Districts, renamed Coast Defense Commands in 191 ...

Field Artillery Branch (United States)
The Field Artillery Branch is a combat arms branch of the United States Army that is responsible for field artillery. Historical background The U.S. Army Field Artillery branch traces its origins to 17 November 1775 when the Continental Congress, unanimously elected Henry Knox "Colonel of the Regiment of Artillery".
